tour de farce
a performance covering a ridiculous set of non-sequiturs or otherwise wildly unrelated achievements and situations
The band's performance surprised the large gathering with a tour de force of popular (and some not so popular) music from the 60's, 70's and 80's. The variety spanned from Elvis to the Eurythmics, Black Sabbath to The Beatles, Mungo Jerry to Lady Smith Black Mumbazo, Santana to Simple Minds. Maybe it was more "tour de farce"!
