The Alley Cats are an American doo-wop group singing in a cappella.

The group originated in 1987, when a doo-wop revival program was occurring at Fullerton College. Two men, also the group's future founding fathers, Mando Fonseca and Royce "The Voice" Reynolds, decided to start an a cappella group. Two additional members along the way, Todd Dixon and Andre Peek, materialized and the foursome gained notice. Since then The Alley Cats have performed for many audiences, ranging from elementary school fun nights to The Tonight Show with Jay Leno, as well as opening for Leno at his Las Vegas shows. The Alley Cats's sound has been heard as well at The White House.
