‘Give Peace a Song’ also features over 35 minutes of bonus material including television interviews, a John and Yoko press conference and Petula Clark’s visit to the bed-in.
This is confusing, because Amazon.com lists the DVD as having been released in 2006. One of the DVD chapters is “Petula Clark Visits The Bed-In.”
I don’t know if the NME item is something old that was posted in error, nor do I know how much footage there is of Pet on the DVD, but it sounds like a video worth seeing.
