It just isn't the same without the euphonium playing the solo. . .

Here is a link to the Korea Brass Choir playing Holst 2nd suite in F. I think the arrangement and the group are really good (although I think they should have used a euphonium, my unbiased opinion).

Korea Brass- part one; 1st and 2nd movements

Korea Brass- part two: 3rd and 4th movements
