Are there any books containing what I can only call organ "fanfares" to intoduce hymns? Especially Christmas ones (at this time of year). I'm thinking things like Ralph Vaughn Williams' wonderful intro for Old 100th - something like that. Not too long but can be realised fairly easily on the organ and making heavy use of reeds etc.
I'm in a particular urgent need for one for "O Come All Ye Faithful" in the coming week or two.
Any suggestions gratefully received. I'd have a stab at composing my own but am a bit short of time (and ability).
