At one point during McCartney’s gig last month he said to the crowd “we know when we’re doing a new song because we don’t see all your phones out”. A new song is often a cue to go take a break at a gig. But every classic hit was new once. Look at this clip of The Killers doing Mr Brightside to a small crowd in 2002 who are not that interested. This song now closes festivals. Anyone else have other examples of new songs before they were famous?
