The Springstreeters are an all-male a cappella group founded in the early 80's. We sing, we dance, we do other stuff too, we're not really sure what that means. We go on tours and roadtrips all over the east coast and into the middle of the country too sometimes. Auditions are held during the first week or two of classes.

Also, somewhat less importantly, the Springsteeters were the inspiration for the name of the Williams College streaking team, the Springstreakers.
