Ever heard of the album A Trick Of The Tail?

I'd like to see how well you'd do when you have to learn a dozen or more songs, by various musicians, across numerous genres, probably in the same of about 1-2 weeks, and then have to play them with almost certainly little or no rehearsal. Kenny Aaronson happens to be a top flight bassist. By 1984, he'd already logged 13 years as a professional musician going from playing with the bands Dust and Stories to logging time with Foghat, Derringer, Billy Squier, Billy Idol, Dave Edmunds, Bob Dylan, and many others. Kenny was in the band HSAS, with Sammy Hagar, Neil Schon and Michael Shrieve, and the album they made, Through The Fire, is a criminally underrated item.

You'd probably mess up too if you were given a week or two to learn an entire night's worth of music, backing numerous musicians across multiple genres, and with little or no rehearsal.
