He “sang“ Jumping Jack Flash on the karaoke in my old west London local during an Earls Ct run in the early 90s. I missed it as I avoid karaoke. Apparently he was awful, struggling to keep a straight face. His marras were in tears at the bar according to the staff. Twas a pic in one of the tabloid pop music pages a few days later.Twice at the old Giants Stadium (Rising, consecutive nights - amazing), once at the IZOD (Wrecking Ball - their first NJ show after Clarence passed, and Clarence's nephew played sax - not a dry eye), and once at MetLife (might have been Wrecking Ball as well - was about 10-11 years ago)
Obviously the dream is the Stone Pony (or Wonder Bar) in AP - I'm there quite often and he shows up quite often unannounced, but never when I'm there and I'm always reading about it after the fact!
