Fleetwood Mac - And they lived happily ever after

British-American rock band the residence of which we will grant to London for convenience sake - could have been California just as well. 

The band name? A combination of (parts of) the last names of drummer Mick Fleetwood and bassist John McVie. 

Active: 1967-present, GBR/USA
