longest career

I also added a 1962 limited run Rolling Stones acetate for consideration. In addition to extending their recording career, it feature an otherwise undocumented (here) lineup.

If we could only get the Isley Brothers in, they'd easily beat the Stones for longevity. I think they're currently at 64 or 65 years (1957-2021).

I’ve added the new Temptations record, which expands their recording career to 60 years.

I realised I made my first recording at about 3 months younger than what Malone did. I'm obliged to still be alive and recording my goofy noise at age 97 to try and beat the record. I guess a bunch of other youngsters out there are working towards it too, but whether they're documented in B2B is another matter.

I’ve added Marshall Allen’s earliest recording (presumably). which will move him past the 70 year barrier.

Sir Paul McCartney says he has employed artificial intelligence to help create what he calls "the final Beatles record".

He told BBC Radio 4's Today programme the technology had been used to "extricate" John Lennon's voice from an old demo so he could complete the song.

"We just finished it up and it'll be released this year," he explained.

Sir Paul did not name the song, but it is likely to be a 1978 Lennon composition called Now And Then.

The upcoming new Stones album is in queue.
