Recordings of John Lennon's killer describing the late beatle's horrific 8 December 1980 assassination are to be aired on television in Britain and America.

The tapes, recorded in the early 1990s by a journalist writing a biography of Mark David Chapman and his crime, trace the killer's "compulsion" to murder Lennon.

On the recordings, Chapman admits, "Nothing could have stopped me. It was like a train, a runaway train."

The chilling tapes will be broadcast to coincide with the 25th anniversary of Lennon's death next month (DEC05) on British network Channel 4 and US broadcaster NBC.
