Former TV:n Orjat member Jarmo 'Jabi' Hirvi formed Wrum in January 1980. By March the lineup had been established as Jabi: vocals & guitar, Raine Potinkara: guitar, Jari Lehtinen: keyboards, Juha-Matti Makkonen: bass & vocals and Kari Salminen: drums. The band played at Ruisrock festival that summer, and made their debut single on Fifty-Fifty label. Takapihojen rock-tähdet/Rocktähti was a great opening. The A side became a kind of theme song for them, and a minor hit.
