This clip is apparently shown every New Year's Eve in Sweden at midnight.

Recorded at same time as Show Express for later broadcast (you can recognise the background and their hair is the same - plus only Frida and Agnetha have changed outfits, but Benny and Björn have not).

Here they perform Happy New Year which was also shown on Sur Son 31 the same night (together with a recorded skit and New Year message for French fans).

ABBA wore the pink/purple/lilac/burgundy silk suits they had first in the Happy New Year and Felicidad PROMOs; also worn for Stars and that Björn had worn for Aplauso.

Release information:
This performance has been released on the CD/DVD Super Trouper Deluxe Edition.

1. Agnetha forgets to sing the the last line of the first chorus ("you and I") and, realising her mistake looks at someone off-camera, tilts her head, shuts her eyes and bites her lip.
2. In the second verse, Agnetha catches Björn's eye and smiles at him at "in the ashes of our lives."
3. Benny at the end - he doesn't seem to know which camera to look at!
