GuitarWorld.com has premiered a video of Eric Clapton rehearsing for his 16 January 1992 performance on MTV's Unplugged. Check it out here. The video features Eric and his band — all of whom play plastic kazoos at one point — running through Jesse Fuller's "San Francisco Bay Blues." The rehearsal performance is taken from Reprise Records' new deluxe 2CD/DVD version of Clapton's Unplugged album. The new set has more than an hour of previously unseen rehearsal footage.
