ABBA were interviewed by Valerie Singleton during their promotion for ABBA - The Movie. This was probably pre-recorded earlier in the day and broadcast on the teatime Nationwide programme (around 6.30pm).

Their appearance on Blue Peter around 4.45pm that day was live and they then had to leave for their film première meaning they couldn't have filmed this for Nationwide live. Two clips from ABBA - The Movie were screen as part of the interview.  NOTE that the link to ABBA - The Movie is of the Australian footage. There is a separate entry for the Swedish footage.

About two seconds were broadcast on 5 February 2009 in a documentary about this 1970s TV news programme called It's Time to Go Nationwide. Those two seconds were part of a compilation of superstar guests who had appeared on the programme - and up until then I did not know they had appeared on Nationwide.

The clue was shown at the Kaleidoscope Music Event (an event for TV afficionados) at 4.45pm The Talbot Hotel in Stourbridge (near Birmingham, England) on 7 June 2014 with entrance fees going to charity.

A few seconds of the interview was included in a video show at the end of the ABBA Super Troupers Exhibition at the O2 in London which began 6 December 2019 (and currently which was due to end in August 2020 but a global pandemic forced its early closure in March 2020).  See video section for a sneaky snapshot of that.

On Saturday 6 April 2024, as part of the 50th Anniversary celebrations, a short snippet was included in More ABBA at the BBC.   

So we still need the whole interview to be re-broadcast somehow!
