MP3 DEMO:
F2769. IT TAKES A WHOLE LOT OF HUMAN FEELING - Eb to E to F
key - Eb to E to F - vocal range - Eb to A (optional D and C) It's more a feel range than a definite top note.
Wonderful song from the 1971 Broadway musical "Don't Bother Me, I Can't Cope, written by Micki Grant. Here's a very cool Trio arrangement that is in the same keys as the wonderful Carmen McRae version but the arrangement is all mine.
Same arrangement as F2768 except a full tone lower.
