Billy Joel fears he'll never be able to top one private performance at a Jon Bon Jovi party, where Paul McCartney, Bruce Springsteen, Roger Waters and Jimmy Buffett joined him for an impromptu jam.
The supergroup to end all supergroups came together at Bon Jovi's house last year (08) - and Joel still can't believe what happened.
He recalls, "We all got up and played a Pink Floyd tune, Wish You Were Here, and I Saw Her Standing There and Long Tall Sally."
