What if Lindsey had toured with FM in 1987?
 

What would the set list have been like?

I wonder if Big Love would have been performed with the whole band then, instead of as a solo?

Would Lindsey have played some of his other songs from Tango? And if so, which ones?

For comparison, here are some of the songs actually performed by FM for that tour, in random order. Feel free to make any additions or corrections, please.

Say You Love Me
The Chain
Dreams
Go Your Own Way
Brown Eyes
I Loved Another Woman
Gold Dust Woman
Rhiannon
Sara
You Make Loving Fun
Don't Stop
Blue Letter
Songbird
Stand Back
Has Anyone Ever Written Anything
World Turning
Oh Well
Seven Wonders
Little Lies
Isn't It Midnight
Everywhere
Tear It Up

I think there are older threads on this exact topic. If Lindsey had toured I don't think Has anyone ever written anything for you and Stand Back would be in the set. Sara was not done in the United States (only in Europe I believe). Tear it up was not played until the farewell tour late 1990. I also don't believe Oh Well would have been performed.
We probably would have gotten, Not that funny and I'm So Afraid and some variation of Big Love.
I also believe the band would have disbanded for many years after the tour.

Good chance you would’ve gotten Tango as well.

I feel like Lindsey would have performed either Tango in the Night or Caroline, but not both. I like both songs about the same, so I don't really have a preference, but Caroline might be more of a crowd pleaser.

FM tended to only play a handful of songs from their later releases, so I really think if Lindsey had been with them and he had sang 1 or 2 of his songs from Tango, then Christine wouldn't have played isn't It Midnight. And that would have been a crime!

I agree Caroline and Tango have a similar vibe and probably don’t need to both be played. But Tango was the title track for the album and tour.

On With The Show was partially the tour that didn't happen in 1987. i thoroughly enjoyed much rockier sound of live Little Lies, for example, vs the pop album version. something that LB has typically done with FM songs live vs album.

The OWTS tour was fantastic and that it likely ends up being the last time I will see Fleetwood Mac, I am glad that it finally happened. The Rumours 5 back together for one last tour despite over 15 years of not ounce of hope that Christine would unretire and come back. And it definitely was in some ways the Tango tour that never was - never thought I'd hear anything but Big Love from that album again. To hear not only Everywhere again, but also Little Lies (agree that it was more rocking than the 87-90 versions) and the real surprise of Seven Wonders giving four Tango songs in the set...that was just awesome. I would have loved Tango in the Night and Isn't it Midnight as well but you know....take what I can get.
