I like the guitar work in Hotel California, too. But is that really technically called soloing?
It feels so much a part of the song's melody line that I tend not to think of it as soloing but rather as an integral part of the song.
Solos suggest to me a free form style of improvisation that doesn't necessarily support the overall theme of a song but is rather a departure from it that somehow augments it without deviating so much as to sound like a different song.
David Gilmour's solo at the end of Paul's "No more lonely nights" really departs from the song's overall melody but somehow it fits and it sounds great. I think it's an absolutely fabulous solo for Fab Paul's fab song!
Now that I've written this, I'm not so sure of my original assumption. Am I wrong about this?
BTW: I wish Gilmour and Paul would play together again on another song.
