Jett formed the Blackhearts. Laguna recounted, "I told Joanie to forget the band and support herself on the advance money. There was enough for her but not for a band. She said she had to have a band. And I believe to this day that it was the Blackhearts, that concept, that made Joan Jett." She placed an ad in the LA Weekly stating that she was "looking for three good men". John Doe of X sat in on bass for the auditions held at S.I.R. studios in Los Angeles. He mentioned a local bass player, Gary Ryan, who had recently been crashing on his couch. Ryan was born Gary Moss, and adopted his stage name upon joining the Blackhearts in 1979, in part to cover for the fact that he was only 15 at the time. Ryan was part of the Los Angeles punk scene and had played bass with local artists Top Jimmy and Rik L. Rik. He had been a fan of the Runaways and Jett for years. Jett recognized him at the audition and he was in. Ryan in turn recommended guitarist Eric Ambel, who was also at the time part of Rik L. Rik. The final addition to the original Blackhearts was drummer Danny "Furious" O'Brien, formerly of the San Francisco band the Avengers. This line-up played several gigs at the Golden Bear, in Huntington Beach, California and the Whisky a Go Goin Hollywood before embarking on their first European tour, which consisted of an extensive tour of the Netherlands and a few key shows in England, including the Marquee in London.
