I think it was 2011 when Offspring played festival in Holland, NOFX played couple of hours before Offspring who headlined, and there was interview with Fat Mike who said he's looking forward to the Offspring show and they are friends of them...but i am personally not a NOFX fan, nothing against them some of their albums(later ones..) are not bad, but i don't like their sense of humour... otherwise who said Days Go By was last album released on Columbia?, as far as i remember, Splinter was already supposed to be the last one...
