Checking out your groups  website, I picked up they are obviously in Glasgow!

Couldn't find an actual location or what 'toon it is?

Also I see some are also members of a Scouting group.

Viewing pics of your panto, I can see it's mainly Front Of House lighting ['Y' Position], although in one they used 'floats' [[footlights] int 'Z' (deck) position} hence the shadows on the back drop cloth. 

You could use more wash light from ['X' position] over head & side light which will help.

From your post as you have two FOH lighting bars & only one lighting batten on stage, I'd suggest utilising the No2 Front bar & re hanging it on stage, if thats possible, or add at dead hang at least an aluminium tube/pipe as a cyc batten upstage. You will find it easier to light if you have at least two light battens [LX] on stage.

{a lot of techies refer  to these as 'LX' these days, believing it means 'Light Effects', I believe it actually stands for 'Lighting 'X' (overhead) batten, as in the old description of Boarder X light Battens [flood troughs - strip lighting]}

I note there was one QI flood light focused on the the upstage. These are quite cheap these days, as they are all knocked in China. which can be utilised effectively as wash lighting, with a number In a row, as either Boarder &/or Cyclorama lighting. In fact a lot of commercial style lamps can work well, as theatre lighting. The Small diachroic spot display lamps, make excellent mini high light spots & not bad 'Floats' [footlights] either, as a special feature. If you scrounge around Salvage or Reclamation Yards, you can pick a myriad of lamps 7 lighting fixtures, for less than a song. this is also a good source for tube/pipe to use as light battens, along with second hand gear for fiying it up. Further 'Skip Surfing' on Industrial Sites can yield a wealth of usable equipment & materials.

Scout around & become friendly with other theatre & Amdram groups in your area. Get to know their techies, this can be a great resource to glean tips & even borrow gear & kit from. Especially the Proeatres which normally chuck out old gel into their wheelie rubbish bins. Nearly all of the discarded cut gel can be reused, after they do a rig colour change. as the Lamps are usually larger & the gel only washed out in the centre, from hot spots.

This will save you a packet by re-cutting to the frame size you use or sticky taping it to together.

years ago when i worked in pro venues, I would contact the local Amdram groups & get them to supply a rubbish bin. Which was kept backstage & all used gel would be dumped in to it. you will need a few different brand colour gel swatch books. It will take you time going thru the myriad of colours, cutting & marking them with the respective colour number in white china-graph. But well worth it & good training for future would be techies in your mob.

However all that waffle is not getting the barren a bottle!

If you have parcans use them, but as you would know, they are blat lamps similar to floods & beyond rotating the element hot spot, this is the only focusing that can done. They are particularly good for cross stage side lighting, to fill the odd hole in the wash or ['Z' (floor)] up-lighting specials.

With the floats[footlights] you have these would be better hung behind the proscenium arch, for general wash coverage, pointed toward upstage,so the beams only go as far as the back cloth tail batten. [if they separate electrical circuits, even better to give you different colour wash] The P56's can be used as side & front fill, however if you get Fresnel [soft edge] spots they will give you an even colour coverage & can be adjusted to different beam sizes. Profiles [hard edge] spots will help you as specials & with using GOBO's & other image effects.

I see there is listed on the Amdram theatre site database a couple of groups in Glasgow, who are probably near you & I'm sure would help. http://www.amdram.co.uk/forums/index.php - http://www.amdram.co.uk/forums/index.php  The Apollo Players who use the Kings Theatre there, seem a likely mob to checkout?

In fact the Edwardian theatre depicted on their site, reminds me of the Alhambra theatre, that used to be in Waterloo Street. Which is probably a Bingo Hall now or a car park?

Besides doing shows there as a young bloke, we used to travel up from Tyneside with the Newcastle Gang show, each year, to see the Glasgow Gang show, when I was a young 'gangster'.

Another thing with parcans if you use them on the FOH 1 or 2 Bars, is cross light light them. also you can use home made 'dough nuts & snoots' to concentrate & reduce the beams.

Try & use Ali tube in the same diameter as the scaf pipe or that fits your lamp 'C' hang clamps. Ali is far lighter than using water pipe. They normally are available in 4m lengths, which with Leg Drops at both ends would fit your stage nicely.

Having only 1m fly height above the 'teaser' on the pro, makes for a problem, but using 'Boarders' as masking will give you a wee bit more head space to fit light battens.

Do you use dimmers & hows the lighting controlled?
