about us

Proof of the Pudding was founded in 1975 as Yale’s first jazz and swing a cappella group! In the 50 years since then, we’ve expanded our repertoire and enjoy singing everything from retro jazz standards to new favorites like Lorde and Lake Street Dive. Known for our love of music past and present and our incredible sisterhood, Proof loves to show audiences from San Francisco to Seoul that, when it comes to the talent of an SSAA jazz group, the proof really is in the pudding.
