They're turning a 220-year-old Ambridge building into a cool place for local music fans to visit. April 5 is the targeted opening date for the Performing Arts Legends Museum (PALM), which will display musical artifacts and instruments in themed rooms. The 1950s room includes items like Elvis Presley's yearbook, Perry Como gold records for "Hot Diggity (Dog Ziggity Boom") and "Round and Round," and an authentic '50s diner booth, straight outta TV's "Happy Days," with a tabletop jukebox of that era. In the 1960s room are instruments, outfits and autographed photos from Pittsburgh jazz and blues aces like Walt Harper, Harold Betters, Joe Negri and Chizmo Charles, plus a stage jacket from The Vogues ("5 O'Clock World").
