Thanks for posting - I'd never seen that.
I saw them just after The Mix Up came out and MCA biffed the opening of Triple Trouble twice, but the second time they just rolled with it. Makes the set just that more memorable.
Watching live hip-hop, especially Beastie Boys, gave me so much more respect for tour DJs. Maybe it's easier nowadays, but when rappers would blow their lines, come in late, come in early, etc., the DJ had to figure out how to draw a break out/cut it short, maybe had to scratch on one side while rewinding on the other, etc.
