While attending Amherst College (Class of 1970), he was an active member
of their singing (mainly A cappella) choral group, the Zumbyes. Singing
bass, he appeared on at least two of their yearly albums. One issued in
1968 also featured future actor/writer/singer,
Stephen Collins. David, himself, was featured on the group's 1970 LP, where he was the featured
soloist on the song "Daddy". He also did the arrangement on the song
"Taste of Honey" for the group on that same LP.
