I think I have to give it to Legs. The connection I was looking for was that in each case the latter had discussed Uganda with the former's partner yet both had continued to perform together. Jones accepted that Pallenberg had moved her affections but, no doubt helped by his prodigious intake of alcohol and drugs and the ready availability of replacements, carried on playing with the Stones until he was ousted. When Patti went off with Eric, Harrison brooded for a while but later toured with Clapton as his guitarist - and Clapton, of course, was effectively MC at his 'memorial' concert.
For my mind, Ayers and Cale get the prize. On June 1 1974 Ayers, having disbanded Soft Machine and disappeared off to France to drink wine, was due to play something of a comeback gig at The Rainbow in north London, with Cale, Brian Eno and Nico as 'warm-up' acts and, it's rumoured, then forming a kind of art school supergroup.
Unfortunately, Mr Cale discovered Mrs Cale in bed with Mr Ayers earlier in the day, resulting in a less than amicable performance at the gig and an interesting interaction between the two in the photo on the cover of the album recorded that night.
Over to you, Legs...
