In early 1981, Craig Adams (bass) joined the band and they started to use a drum machine, which was christened Doktor Avalanche. Ben Gunn joined the band as a second guitarist by the end of 1981 and this line-up recorded four more singles and two EPs during 1982 and 1983.

Document 3: Messin' with the Boys: Messin' with the Boys is the second post-Runaways album by Cherie Currie, released in 1980 For this album Currie worked with her identical twin sister, Marie Currie. Their band was called "Cherie and Marie Currie". Marie was a guest vocalist on Cherie's first album, so Marie went on tour with Cherie to support her first album, "Beauty's Only Skin Deep". When Marie would join Cherie on stage to sing the encores the audience would go wild. So Cherie ran with the idea of two blonds are better than one. The idea paid off because "Messin' with the Boys" received more radio play than "Beauty's Only Skin Deep", and their song "Since You Been Gone" made it to 95 on US charts. The single "This Time" and the album Messin' with the Boys made the top 200 on U.S. charts. This makes Messin' with the Boys Cherie Currie's most successful album. "I Just Love the Feeling" originally surfaced on the 1974 album, "S.S. Fools" by the group of the same name. Cherie duetted with that group's lead singer, Bobby Kimball, and wrote the additional lyrics in the second verse.

The group had originally been signed to the label when it was run by their original producer Lou Adler, but by 1971, Dunhill's distributor, ABC Records, had purchased the label and discovered the clause in the group's original contract. According to their contract, the group had to produce one more album, or else be in breach of contract and subject to possible fines. Although the album has some memorable songs, it is considered a disappointment by fans and critics. Nevertheless, the album sold moderately well. (#84 on the Billboard Pop Albums Chart.) It was produced by John Phillips. Michelle Phillips wrote later in the liner note of a Mamas & Papas CD compilation that the album "sounded like what it was, four people trying to avoid a lawsuit".
