Performance Diploma - repertoire advice

[jmh3412]

Help - I'm finally catching up with performance qualifications and would appreciate it if colleagues could give their advice / comments on the following pieces, which I do not know.

This being England - it is likely that they will be performed on EEb although BBb isn't out of the question.

Harold East Sonatina
Jennifer Glass Sonatina
John Golland, Tuba Concerto
Bernard Heiden Concereto
Michael Hopkinson Concerto
Jan Koetsier Sonatina
Claude Pascal Sonate en 6 minutes
Pierre Petit Fantaise for tuba
Rogher Steptoe Concerto
David Uber sonata
Christopher Wiggins Soliloquy X for Solo Tuba

Many Thanks
