As expected, Billy Joel's Friday night (August 10th) return to Boston's Fenway Park held a few surprises. Jambase.com reported that J. Geils Band frontman Peter Wolf -- a local legend and old friend of Billy's from the early-'70s touring circuit -- joined him to perform the Geils Band's 1982 six-week chart-topper "Centerfold." Def Leppard lead singer Joe Elliott also took the stage for a show-stealing rendition of "Pour Some Sugar On Me." Billy tipped his hat to the Beantown crowd by playing a bit of Boston's 1976 classic "More Than A Feeling," led by Billy's sound-alike guitarist Mike DelGuidice.

Yesterday (August 12th), in celebration of her third birthday, Billy posted a video of his daughter Della Rose on Facebook performing a bit of his 1980 hit, "Don't Ask Me Why" live from the family's kitchen. Della is Billy's older daughter with fourth wife Alexis Roderick. The couple also has a one-year-old daughter named Remy Anne Joel.

Billy's eldest daughter, singer/songwriter Alexa Ray Joel, has just announced her latest stand at Manhattan's Cafe Carlyle, which runs between September 25th and October 6th.

Billy Joel, who this year is celebrating his 51st anniversary in the business, was barely in his teens when he realized the power that his musical talent held: "There's a wizardry to it, there's kind of a sorcery to the manipulation of sound. I mean, I was just a little guy; I wasn't a real social butterfly. I'd be at somebody's house and I'd kind of wander over and play the piano and it enchanted other people. And when I came of age and started liking girls, I realized, this is better than a sports car (laughs), y'know? I play the piano and I'd look up and there's a girl, I play a little more, there's another girl; I said, 'This is great.' I recognized the power that's inherent in music."
