In answer to various requests, one or two responses, mainly on lp, though.
"Challenge & response" - as Brain Bowen pointed out, on an lp entitled "Summer Festival", played by Box Hill Citadel Band from Australia, recorded live at the Fairfield Hall, Croydon. I must say, having played this on BBb bass, it is one I reckon is better to listen to than to play - lot of work down the bass end for little effect!
"Melodies of Dvorak" was recorded on an old Canadian Staff Band lp, "Gospel Train", and also by Manchester Citadel Band on "Sounds Mancunian" (1979).
The march "The Golden West" is written by Dudley Bright, currently Principal Trombone in the LSO and Bandmaster at the Ilford Corps. It was recorded by the Canadian Staff Band on the lp "New Horizon", and also appears on a double cd they produced with the Chicago Staff Band in 1999 entitled "CSB/2...Together Again."
"Lord of the Sea" was included in the Meet the Composers festival at the 1978 congress, played I believe by Enfield, but unfortunately only the second half made it onto the recording. It also appears on Birmingham Citadel's lp "Poem" (1989) and the double lp "Festivity", recorded at the Albert Hall in 1982 - not sure offhand which band, or whether it is all included (may be in a vocalised version).
Mention was made of "Fusions" and I was sure I had a recording, but it does not appear in my index - may just have been taped from a "Bandstand" broadcast.
