"I'm obsessed with old English pianos. My flat is full of them. People want to get rid of them and I take them in so I've become a piano orphanage. I have three in there right now. One of them is completely broken so I'm doing it up. I'm learning to tune them, too. I don't have any room - I can't even walk around. It's like a prison in there. I'll have to sleep on them." British singer Tom Odell takes pride in his pianos.
