I'd like to suggest inviting the Upper Lower Hallamswick Carol Singers this year. I know it'll be out of season and they'll charge double, but you'll get it all back via the beer tent anyway; Especially if you lay on a few casks of that Yorkshire Tractor Diesel Oil. Eeh, bah gum. It's a reet good brew is that. The 18.4% strength, that is, not the 9.2%.

Come to think of it, they could do a few workshops. EG.,

How To Stand Upright After 18 Pints.

How To Hold Your Pint In One Hand And Your Songbook Between Your Teeth, Whilst Using Your Other Hand To Turn The Pages.

How To Cram Huge Numbers Of Carol Singers Into Impossibly Small Spaces.
