The group moved from Helsinki to London and continued to gain fans and influence the music scene there. Yaffa played bass in all the Hanoi Rocks albums released in 1980s. In London, Yaffa, along with Hanoi Rocks bandmates Nasty Suicide and Razzle, as well as Knox of the Vibrators, recorded an album under the name Fallen Angels. Knox continued to perform as Fallen Angels after, though the Hanoi Rocks members including Yaffa never played with the band on stage.
