I must have heard it somewhere.
I didn’t realise what this song was about before. Sometimes I listen to and hum along to things for years, (even decades), without really ‘listening’ to the lyrics.. This one is about a lady called Billie Jean who rocked up to Michael Jackson and claimed she’d had his son.
I imagine that over the years he probably had quite a lot of women claiming he was the father of their children. Not necessarily because he was a big lady’s man. But more because there’s a lot of nutters out there.
