The Badfinger video was a BBC item...
two points...
All BBC live appearances had to have a different mix if they were "miming" for MU compliance reasons, so lots of those TOTP (or similar) differ from the originals...
At the end you see a "blond" presenter who has no become the most vilified person in British "celebrity" history - 50 years of undetected and unbelieved sexual assaults ranging from kiddies to elderly... his family have now dug up his remains, smashed his marker (which had "It was fun while it lasted") and had his remains cremated and scattered so he has no mortal place to note he passed this way... lots of editing to remove him from BBC recordings going on... his story is truly sickening...
Badfinger were brilliant but so tragic, and as for the lyrics to Without You, considering his demise...
