ABBA appears on this frequently repeated item on BBC News 24, in which tribute is paid to stars of entertainment and sport who have passed away in 2017. Very sadly, this included presenter Keith Chegwin, who is shown with ABBA in 1976, on the Saturday morning show Swap Shop. Keith is asking Agnetha how long it took to record a particular album. Agnetha hesitates before replying 'I think it took between two and three years'.
The clip edits out the context of this question. A moment earlier Keith, bless him, had been told by Frida that the album in question was ABBA's Greatest Hits
