From Amateur Transplants ADAM KAY'S SMUTTY SONGS

Amateur Transplants frontman Adam Kay sits at a grand piano and sings smutty songs. With sell-out tours and Edinburgh Fringe seasons, his cutting-edge, darkly humourous re-imaginings of pop and rock classics have gained him a cult following across the UK. His songs have over 20 million hits on YouTube, including the iconic London Underground Song, and have been in the iTunes comedy top ten consistently since 2008. This show is probably not suitable for your elderly maiden aunt.

NB Unlike the majority of musical comedy, this is actually funny.
