The Mysterians
Following the single's success, Locomotive recorded an album at the Abbey Road Studios in London with producer Gus Dudgeon. By this time, however, the band decided to perform more progressive rock, based around Haines' keyboard skills. Because of their uncertainty over how it would be received, the record company delayed the release of the album. A single, a version of a Question Mark and The Mysterians song, "I'm Never Gonna Let You Go", was released but failed to make the chart. Haines left the group in 1969, reportedly turning down an offer to join Black Sabbath and eventually forming the Norman Haines Band.
