Regarding the Walton/Howarth Spitfire Prelude and Fugue, the Philip Jones Brass Ensemble recorded it on an album entitled Fanfare on the Argo label back in the mid 1970s and it's on at least two currently available compilation PJBE discs, but I'm not sure which ones! I think it's on Greatest Hits (2 disc collection) and British Music for Brass which was deleted and then re-released last year. Greatest Hits is only available via the Internet, but the British disc should be available from larger HMV stores as well as the Internet. (if I've got the compliations right!)
From a brass ensemble take, (I know that wasn't asked for, but I will anyway!) I'd like London Brass to record Pictures at an Exhibition as what I would consider to be a fascinating alternative to the PJBE recording. Alternatively, (again for brass ensemble) I'd like to hear a recording of Paul Patterson's Deception Pass.
Brass band wise? I'd like another band to record Suite Gothique. Apologies if this offends, but I wasn't impressed with Dyke's recording on The Essential Dyke - President's Choice! (Rest of the CD's excellent, mind!) Also, I'd like to hear a band record Harold Nash's arrangement of Brahms's Variations on a Theme of Haydn (used, I believe as the old section section choice for the Nationals in 1987? A very taxing sop part, but I'm sure many of our top bands' sops would do it justice)
