Roy Harper - Exercising Some Control lyrics

I've got a dog he's like a two ton frog I call him some control yesterday I took him for his walkies in the park he's a beautiful thundering soul at first he never took a fancy to any one wondering by until a big fat cop came ito his sights and he had to know the reason why so he took a little piece out of the gentlemans leg and the gentleman was sore supprised so limping up to me he whispered quietly "what are you playing at?" "I'm exercising some control.. oh oh " Sorry, can't remember all of second verse _ Mike.
