The Seekers were on top of the pop world when they announced that they were splitting up in 1968 and decided to bow out with a goodbye concert filmed by the BBC. They included all of their major hits with comedic skits and even Judith Durham playing a piano solo - All backed with a large orchestra.
It proved a ratings success with over 10 million viewers tuning in. A great record of the group at the height of their popularity, but sadly the BBC wiped their colour copy of the concert and now only black and white tele-recordings exist, it could be restored if they would make the effort - That's the least they could do for yet another example of cultural vandalism.
