"We're a very musical family, and we actually play as a band most weekends," said Annie Houseago, Harry's mother, who works as a music teacher. "My husband is a drummer, and my other son a pianist so we play a lot of charity concerts together. We've always been very musical, and I sing and play guitar. I taught Harry to play when he was three, although he's now a lot better than me. "We loved the Tamiflu song when we heard it, so we've uploaded the song to YouTube, and hope it will do well. We're incredibly proud of Harry."
