Just wonder with a friend this weekend enjoying some dvds and having a good time...

When some artist play or sing one song with them on stage, The Stones pay something to do?

Will be the same payment to Eric Clapton, Bob Dylan, Eddie Vedder, Angus and Malcolm Youg to Justin Timberlake, Taylor Swift,John Mayer, Katy Perry???

Or they only play for friendship?

Anyone knows os has been involved on a this kind of contract?

Methinks the guests do it for free (it's great exposure) and they sign a release allowing the band to use their spot for whatever use they want (CD dvd YT vid).

not sure but few people do something for nothing these days. i would imagine any guest spot would have to be paid for.

I wonder if it works the other way around as well:

Taylor Swift with Mick Jagger - Satisfaction (Nashville, 26 Sept. 2015)

Some of the guests of the Stones should have had to pay to share the limelight and be associated with them.
VIP on stage duet with Mick - $10,000, and have your name and image with the Stones splashed around for all to see.
