In very unfortunate news revealed yesterday, MCA, nee Adam Yauch, of the Beastie Boys has cancer in his parotid gland and will begin undergoing treatment next week. Yauch, with longtime bandmate Ad Rock at his side, made the announcement candidly and fearlessly via video.

Enjoy this performance of "Rhymin' and Stealin'" from 1987 and go leave MCA a get well comment on the Beastie Boys Facebook Page.
