In Britain 'Ob-La-Di Ob-La-Da' is pretty much the go-to song for people who want to slag off The Beatles.
I sometimes think this is because they know the lame Marmalade version better which inexplicably was a U.K. no 1 single and not the much spikier original.
It's also hinted at that the song is somehow racist, conveniently forgetting (a.k.a. 'not knowing') that the phrase was African slang and that hundreds of black acts rushed to cover it before the 60s were out.
