After a bit of research - I've ascertained that this clip is from the It's Cliff - A Song for Europe special (NOT the contest, the different appearance for that exists, of course!), filmed 17/02/71, and broadcast 20/02/71.
I can also confirm that as a thumb rule clips of the winners of the national A Song for Europe had their performances sent to some EBU TV stations.
