Led Zeppelin are invited to appear on "How Late It Is", hosted by Michael Wale, as a last minute replacement for the Flying Burrito Brothers. Unfortunately, the tapes apparently no longer exist in the BBC vaults.

Jimmy Page: "This was a pilot for an arts discussion programme directed by Tony Palmer. We supplied the musical slot and played 'Communication Breakdown' live. There were no interviews with us. The programme established itself and developed with more emphasis on music of the day. During the course of its run it had interviews with the likes of Eric Burdon, John Lennon, Yoko Ono and The Nice, amongst others. Unfortunately the BBC tape of Led Zeppelin no longer exists. This was a pilot programme."

News clipping: (April 1969) "Led Zeppelin appear on the first of a new television series entitled "How Late It Is", which is screened at 10:30 this Friday (14th). Produced by Tony Staeacre, the programme will feature a further Zeppelin appearance in a few weeks time."
