Two guys that came instantly to MY mind were, of course, Brian May and Roger Taylor. As members of Smile, they released the 45 'Earth' / 'Step On Me' in December of 1969.
Then they were in a crazy little band called Queen. Afterwards, in the '00s it was Queen + Paul Rodgers. They released the Queen + AL 'Live Around The World' in 2020. Various solo and collaborations throughout the years; most recently in 2021, Brian with Kerry Ellis, and Roger with his sixth solo studio album (which debuted at #3 in the UK).
