(NOTE: The 15 January episode has been wiped, but the 25th December episode is still in the archives, so any repeated TV broadcasts of this clip is from that episode and not the original one).
A rare live performance of "Mamma Mia" - sweet clear vocals over a pre-recorded backing. Apparently two versions were recorded: firstly with Swedish musicians only (Caj Gunnar Högberg, Ola Brunkert and Lasse Wellander) and secondly with Swedish and British musicians.
Caj Gunnar Högberg has posted his work permit for the London trip onto the internet. It is valid from 13 to 18 January 1976 so the filming date of 12 January (according to ABBA - The Book) cannot be correct.
This episode has apparently been wiped.
