One of the longest running pop/rock and roll groups in the country started out with the name Chicago Transit Authority. Famous for many hits in the 1970s and 1980s, their rock/jazz fusion proved popular. The band began calling themselves by that name in 1968, and their first album was eponymous. Unfortunately, the actual CTA threatened to sue the band, so the group dropped the "Transit Authority" and grew famous as just Chicago.
