Gilroy met Madonna, then an aspiring dancer, at a party in 1979. They became romantically involved and she moved into the synagogue where Gilroy lived with his brother Ed Gilroy in Corona, Queens. It also served as a studio for the brothers, who at times worked as musicians or comics under the name Bil and Gil.[2] While Gilroy and his brother were waiting tables during the day and performing their comedy routines at night, Madonna was at the synagogue practicing drums.[2] She also began writing songs, Gilroy taught her how to play guitar and they formed the band Breakfast Club.[3] She convinced Gilroy to let her perform her own songs, to which he reluctantly agreed. Madonna promoted the band and they performed local gigs.[2] In 1980, Madonna left Breakfast Club to form the band Emmy and the Emmys.[4]
By the mid-1980s, Breakfast Club consisted of the Gilroy brothers: Dan concentrated on singing, with Ed on guitar. Gary Burke joined the band, playing the bass. Also, Paul Kauk on keyboards, and Stephen Bray on drums.[5] In 1987, Breakfast Club signed a record deal with MCA Records and released the album Breakfast Club. Their single "Right On Track" peaked at No. 7 on the Billboard Hot 100.[6] They recorded a second album that was never released. Their last song was a cover version of the Beatles "Drive My Car", which was included on the soundtrack for the 1988 movie License To Drive.[5]
