Fun fact: Journey had previously toiled for 4 years as a prog rock band, with Gregg Rolie as their primary singer. In 1977, after 3 unsuccessful albums, their record label was fed up with the lack of sales, and basically told them: "Hire a real frontman and start recording pop songs, or else we're dropping you."
So they went out and hired.........
Robert Fleischman.
Fleischman was with Journey for about 3 months in 1977, but due to various clashes (personality/management/musical direction) he was replaced by Steve Perry.
Anyway, while Fleischman was in the band, they wrote and recorded an album's worth of songs......including an early version of "Wheel In The Sky":
