Led Zeppelin were an English rock band formed in London in 1968. The band consisted of guitarist Jimmy Page, singer Robert Plant, bassist and keyboardist John Paul Jones, and drummer John Bonham.

They were originally going to be called The New Yardbirds until The Who's drummer Keith Moon remarked they would go down like a "lead zeppelin". 

Between 1971 and 1975 Led Zeppelin could justifiably claim to be the biggest band in the world

Queen are an English rock band formed in London in 1970, originally consisting of Freddie Mercury (lead vocals, piano), Brian May (guitar, vocals), John Deacon (bass guitar), and Roger Taylor (drums, vocals).

. The group is well known for its sports anthems and classic rock radio staples, particularly the hits 'We Are the Champions' and 'Bohemian Rhapsody'
