Weird music - Selling England by the Pound

The band that came up with Selling England by the Pound was not obscure or particularly odd.  It was Genesis – you know, of Phil Collins fame.  It harks from 1973 and was the band's 5^th studio album.

Apparently the band wanted to indicate their Englishness by the title???  Or is it an allusion to the take over of English music by Americans? We don't know because it is not also the title of a track on the album.
