Bob Marley was famously quoted as saying, 'no woman, no crime'. In this song, Three Little Birds, he sings about how the arrival of three birds on his doorstep cheers him up. But the original cover has no woman. According to the urban dictionary, the term 'Bird' refers to a young woman. And so now the picture is complete as the three 'birds' that cheer up Mr Marley stop him from committing any more crime. Tweety!
