There are some good stories in the liner notes to Dion's Bronx Blues, like hearing John Lee Hooker's "Walking the Boogie" with Willie, the super in his family's building when Dion was a teenager, and years later using the stomping beat from that on his hit, "Drip Drop".
And showing up for a gig at a supper club on Long Island with Buddy Lucas on harp and himself on electric guitar. The patrons showed up in tuxes, expecting and elegant evening on the town and got something entirely different. "They never booked me back after that."
