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 No. 19 on the Cash Box chart and No. 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 No. 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. In 1970, they released two singles, "Nine to Five (Ain't My Bag)" and "Jesus Is Just Alright"; neither charted, and the group broke up soon after.
