Capitol Steps

The Capitol Steps were an American political-satire group that performed from 1981 to 2020. Most of the Capitol Steps' material parodied well-known contemporary songs, usually introduced with a short skit. The songs were interspersed with other routines, including a spoonerism routine near the end of each performance with innuendoes about recent scandals. Wikipedia*
