Peter was always singing and whistling, mimicking people, laughing...mostly at his own jokes.  I remember when we were a lot younger him in the bathroom singing When I Fall in Love.  I thought he had the radio on and it was Nat King Cole singing it. He said no it was himself.  Ofcourse  he emerged from the bathroom making a lot of this and we were never to hear the last of him being able to sing like Nat.  Happy days. XXXXXXXX
