David Cameron has admitted not being "all left or all right" has caused him problems - in drum lessons.
The Prime Minister revealed the problems he had learning the instrument at school during an interview with Classic FM.
"I loved playing the drums and I had a great teacher actually. But I didn't get that far. I got as far as playing the drums on Tie A Yellow Ribbon Round The Old Oak Tree," he said.
"I enjoyed it. My problem was, this will sound like a feeble excuse, but I'm left handed and right footed and actually if you're a drummer that can be a bit of a problem.
"You want to be all left or all right and I was a bit of a mixture. But I remember once having to stand in for a friend who was a very good drummer in a jazz band and standing in for him one evening. And I remember, you know, finding that a real thrill."
Mr Cameron also revealed that he shares at least one personal trait with his bitter Commons foe Ed Balls: like the shadow chancellor he cannot help shedding a tear over The Sound Of Music.
"As we get on Edelweiss I'm reaching for the Kleenex," he said after Mr Balls previously listed the popular movie as viewing material that made him cry, along with the Antiques Roadshow.
"I watch that most Christmas or new year when it comes around."
He said Emma Thompson's performance as Mary Poppins author PLTravers in recent hit Saving Mr Banks was another that had left him emotional.
"Samantha and I were watching it and we both had a lump come to the throat," he said of his wife, who he credited as being the presence that "keeps me sane".
Recounting his "rather odd" proposal to Samantha while they were sitting on a sofa watching Martin Scorsese's gritty crime film Mean Streets, he admitted it had been " quite a challenge" to win her hand in marriage.
"She's a lot better looking. And yes, when I first proposed, she didn't absolutely leap at it," he said.
He stuck to the Hollywood theme by choosing as one of his pieces of music on the show the theme from The Good, The Bad And The Ugly, which he said was one of the familiar Westerns he liked to watch to help him relax.
Another was a song by Mendelssohn which was played at the couple's wedding, which he said reminded him of " sitting there with all your friends and your family in the church and just thinking you know, how have I managed to be this lucky".
The PM's final choice was Elgar's Nimrod, which he said always made " goose bumps go up the back of my neck" and made him " feel incredibly proud to be British".
He said: "Sitting in Westminster Abbey and hearing this, whether it's for a Royal wedding or a service of commemoration or whatever, it's one of those moments you think yes, this is the greatest country on Earth."
He put "building the National Health Service" alongside ending the slave trade, defeating Nazism and the creation of the United Kingdom among "so many things to be proud of" about Britain.
"But I think also the values. You know what Britain stands for, the tolerance, the democracy, the rule of law."
