  My dog (a border terrier) joins in, singing along to the drums. I hear him from the cellar sometimes. Usually he does it at the beginning of my practice then seems to get bored and wanders off. The funniest times have been when we've had band practice at my house and he's spontaneously started singing along to the full band. He also sings along to some tunes on CD/in the car etc. He's a big reggae fan http://www.youtube.com/watch?v=UUM0o...0&feature=plcp
