Jerry Murad's Harmonicats were an American harmonica-based group. The band was founded in 1947; by 2009, it was no longer performing. Originally they were named The Harmonica Madcaps and the group consisted of Jerry Murad (chromatic lead harmonica), Bob Hadamik (bass harmonica), Pete Pedersen (chromatic harmonica), and Al Fiore, (chord harmonica). They reformed later as a trio with Murad, Fiore, and bass harmonica player Don Les.
Pedersen and Gail Wallace remained contributors to the group throughout its existence, working on arrangements and occasionally recording.
