Just got this CD in the mail yesterday. I like it!
You can preview the whole album here:

The first two tracks have pretty big euphonium solos on them. Liner notes say the player is John Storey, who is of course the principal player in the Band of the Coldstream Guards.
You need to get a good ways into both songs to hear the euphonium solos.
