Dear Warren,
Noticed your post is from'03. Maybe this info may still be of use to you. Charlie Chase comedies were produced by Hal Roach studios{the people who gave us Laurel and Hardy, Our Gang,
Thelma Todd and Patsy Kelly,etc}. The musical director for Hal Roach during this era was Leroy Shield. I only know of 1 recording of his, SING SONG GIRL recorded on Victor22548 in 1930. The flip side is SONG OF THE BIG TRAIL. I've seen numorous copies at record shows over the last couple of years. I live in the NYC area. You might want to look him up on IMDb, Amazon.com. I hope this info is helpful.
Regards
