Lonnie Johnson, Playboy Club

This was followed by other Prestige albums, including one with former Ellington boss, Elmer Snowden, who had helped Albertson locate Johnson. There followed a Chicago engagement for Johnson at the Playboy Club and this succession of events placed him back on the music scene at a fortuitous time: young audiences were embracing folk music and many veteran performers were stepping out of obscurity. In short order, Lonnie Johnson found himself reunited with Duke Ellington and his orchestra and appearing as special guest at an all-star folk concert, both at Town Hall, New York City.
