He eventually mastered that one, posting a video from "JM's Unemployment Tube" of him playing the song, warning it was "crap content". After playing the song, May says: "I'm here the rest of my life."
He then called it "rubbish", called people slackers for commenting on it and, strangely, told people what was coming next.

Asked earlier in the week if he will continue on Top Gear, May said the trio came "as a package" and his future requires "a lot of careful thought".
