Because clips on video sites often disappear these links most often aren’t included here, you will find most of them there though. See also ABBA On TV for more information about the shows.
ABBA pre-recorded several tracks (with or without live vocals) for their TV performances and then mimed to them at the actual show. Therefore it’s not easy to tell how much ‘live’ these performances really were. However, even if pre-recorded, they (the vocals at least) still were performed live at that moment and not mixed and enhanced in the studio afterwards.
