I saw Boy George once on the London Overground (Clapham Junction-Stratford) to work on a Monday morning (around July 2014). He was a little chubby at the time....and in a Mint Green Adidas tracksuit.
He tried playing undercover, but he somewhat undermined himself just by sporting gold Elvis sunglasses....as well as sporting a very colourful - and visible to those of us standing on the train - mandala tattoo to cover up his bald patch.
Oh, and having passengers pointing at you saying, “Oooh, look! It’s Boy George! What’s he doing on the train this time of the morning?” as he walked down the carriage didn’t help his cause either. This was around the time (before or after? I don’t have a clue) that the rent boy torture scandal blew up large.
