The Beastie Boys just announced that they're cancelling a bunch of shows and delaying their record release (The Hot Sauce Committee Part I) because Adam Yauch, aka MCA, has cancer in a gland and lymph node. Fortunately they caught it early and it hasn't spread. He's scheduled to have surgery soon. You can see the video they made for fans here.
I've been a Beastie Boys fan since they first formed and was really looking forward to their set at the Austin City Limits Festival. I was also hoping to score tickets to their Austin City Limits TV taping. I'm not sure if they're still planning on making the trip to Austin or not. I hope so but I really hope that Yauch makes a full and speedy recovery soon.
I just read some more about this on Brooklyn Vegan and it appears they have cancelled their ACL appearance.
