Ladies and gentlemen, meet Bessie Lawrence from Grimsby.
Age cannot wither Bessie. Oh, no.
Because while Bessie may seem like a perfectly normal 70 year-old great-grandmother from Grimsby, she has a rather unusual passion.
And that's head-banging at nightclubs twice a week.
"I like a group that's lively, got plenty of oomph, " she explains. "Gets you going, doesn't it?"
It does indeed. Just click play on the video above to see Bessie in action - and then click play on the videos below to see some other people d'un certain âge enjoying themselves waaaaay too much. We salute them all.
