Actor Daniel Radcliffe turned to Harry Potter co-star Alan Rickman's singing coach to hit the high notes onstage.
The 21 year old had to sing the Milky Bar Kid TV theme during his stint in Equus in 2008 and 2009 - and quickly realised his voice wasn't up for the challenge.
He tells Out magazine, "For some reason, I kept inventing a new tune every night, so they sent me off to this guy, Mark Meylan..., to sing."
And he admits the coach was a tough teacher: "He sort of abuses you as you get it right."
