Its called Saving Planet Earth Live and so far we have had a song by Avril Lavigne, a pre-recorded report and now Alan Titchmarsh is interviewing David Attenborough. However, the EPG
says it should just be an regular episode of Planet Earth as does the BBC website... http://www.bbc.co.uk/bbcone/listings/programme.shtml?service_id=4223&filename=20070706/20070706_1900_4223_13853_60
Was this a last minute change? The EPG has EastEnders starting at 8pm but Alan Titchmarsh has just said "Don't worry EastEnders fans, it will be on at 8pm" as if that was a change to the schedule (the subtitles said it was on at 9pm).
