Proof is turning 45
Proof is so excited to celebrate its 45th anniversary in 2020!
What started as a response to the underrepresentation of women in Yale a cappella has grown into a decades-old sisterhood with more than 250 alumnae.
Join us the weekend of February 6th-9th for sisterhood, song, and some jazz that is both sweet and hot!
