Gerry has been offered gigs with many bands but declined them all due to his other commitments in his multi-faceted career. He owns the label Die Laughing Records and all his own released material. The Girl catalogue is owned by Sanctuary Music/Universal under licence to Rock Candy Records.

In 1978, Laffy was a founding member of the band Girl with Philip Lewis. The band recorded three albums and put out two (Sheer Greed 1980 and Wasted Youth 1982) they split up in December 1982. Killing Time was finally released in 1998, and three live albums and an anthology were released subsequently.

After Girl disintegrated, Laffy joined London Cowboys, (with former members of The Idols, Sex Pistols and New York Dolls), which released two albums in 1985.

In 1986 he played guitar on demos of Duran Duran's 'Notorious' album.

In 1990, Laffy founded Die Laughing Records and released his debut solo album Money & the Magic. The song "Shoot 'Em Down" from this album was included on the European soundtrack to the film Highlander II: The Quickening.

Laffy formed a band Sheer Greed with some of Girl's alumni, which put out two albums in 1992 and 1993.

From mid-1997 to mid-2000, Laffy was lead guitarist in Terroristen, John Taylor's band while on hiatus from Duran Duran. Terroristen recorded constantly and gigged all over the United States and Japan, also traveling to Taiwan and Germany.

In 2001, he released a second solo album All Day Long.

In 2005, Gerry was a guest vocalist with ex-Freddie Mercury guitarist Chris Chesney on his album Diabolical Liberties.

In 2007, a third solo album - The Icebox Studio Sessions was released. Self performed, written and produced.

In July 2009 Girl were approached to reform for a 30th Anniversary tour of Japan & UK in 2010. It is yet to be confirmed.

In 2013, after a brush with death after contracting septicaemia Gerry dusted off his Fostex MR16 to record again for the first time since 2007. In the early spring he wrote, produced and performed all instruments on 'Just A Little Blurred' (with a guest Craig Bundy on bass on a reworking of the Girl classic 'My Number') this was released in March. After being hospitalised twice that year Laffy pulled through with such conviction that he even found room to make a second album in the same year. 'Wrecked But Not Crushed' was entirely made by Laffy alone. It was released in September 2013. Both released on Die Laughing Records.

In July 2016 Rock Candy Records re-released the first 2 Girl albums ‘Sheer Greed’ 1980 and ‘Wasted Youth’ 1982. These 2 albums entered the Japanese International import chart at No.7 & 8 respectively proving that even after 35 years and various friendship desolved that this little band Girl (Spring 1979 - Dec 1982) still has a legacy intact.
