In April 1978, Saturday Night Live cast members John Belushi and Dan Aykroyd appeared on the show as The Blues Brothers. Dressed in black suits, fedoras, and sunglasses, Belushi sang lead vocals as "Joliet" Jake Blues while Aykroyd portrayed Elwood Blues, singing backup and playing harmonica.
Their first album, Briefcase Full of Blues, went double platinum and reached number one on Billboard's album chart. The record produced two top 40 hits with covers of Sam and Dave's "Soul Man" and The Chips' "Rubber Biscuit." The Blues Brothers went on tour, even opening for The Grateful Dead in December 1978. In 1980, Belushi and Aykroyd starred in The Blues Brothers, a feature film that chronicled the life of the fictional duo.
Belushi died in 1982, but The Blues Brothers live on with Jim Belushi (John's brother), John Goodman, and other guests stepping in to fill his shoes.
