Sleeper Catcher is their fourth studio album, released in Australia in April 1978. It peaked at No. 4 on the Australian Albums Chart and No. 16 on the US Billboard 200.
The band is shown on the cover of the album playing the Australian game Two-up, and the Sleeper Catcher is a “participant” who retrieves bets left behind by a tardy gambler in the game.
The shown track list is from the US-Version, the original release had a different track order (with the same tracks), and the same cover.
