Bosco played bass in the short lived Darby Crash Band.
The Darby Crash Band was a music project started by Darby Crash and Pat Smear, founding members of Los Angeles punk rock band the Germs, formed after the Germs split in 1980. They recruited bassist David “Bosco” Danford and Circle Jerks drummer Lucky Lehrer and began playing shows in Los Angeles. The band’s set lists would include a number of well-known songs from the Germs’ archives, as well as newly written material. The band never recorded and played only a small number of shows before Darby’s death on the 7th of December, 1980. – WIKIPEDIA Darby Crash Band page
