Introduced by Melvyn Bragg In 1964 a rock group called The Who made their first public appearance at a pub in Harrow. The line-up was PETE TOWNSHEND (guitar), JOHN ENTWISTLE (bass), KEITH MOON (drums) and ROGER DALTREY (lead vocals). Ten years later the same band hold an undisputed position among rock giants. The first programme in a new series of 2nd House examines this phenomenon, and MELVYN BRAGG talks to Pete Townshend , leader of THE WHO.
