One-time owner of the Band Box, a comedy club previously owned by Lou Costello. Among the performers were Maxie Rosenbloom, Buddy Hackett, Polly Bergen, Alan King, Billy Barty, Don Rickles, and Jackie Gleason. For decades, Canter's Deli, which moved to Fairfax Avenue near the club in 1948, has offered the Billy Gray's Band Box Special: an open-faced chopped liver, minced onion, and chopped egg sandwich with coleslaw.
