They practiced a lot during a few months, and wrote their first songs. In May of 1977, the band's name was changed to Warsaw and Mason was replaced on drums by Tony Tabac. Just a month later, Tabac left and Steve Brotherdale was hired as new drummer. It was at the same time that Paul Morley of the NME and DJ Rob Gretton found out about the band and saw its potential. Warsaw made a demo tape with five songs in the Pennine Sound Studios in July, but Brotherdale quit the group a few days later.
