Underground Sunshine was an American psychedelic rock band from Montello, Wisconsin. The group scored a hit single in 1969 with their cover of The Beatles' "Birthday", which hit #19 on the Cash Box chart and #26 on the Billboard Hot 100 chart. The group subsequently appeared on American Bandstand and released a full-length album, Let There Be Light. The album hit #161 on the U.S. Billboard 200 chart, but their second single, "Don't Shut Me Out" (written by David Gates, later of Bread), just missed the charts.
