Looking at Cher's discography and setlist from 2019 tour, I dunno tbh. There's obvs a couple of big songs in there, but I reckon there would be quite a bit of filler.
The shorter 2019 set (closer to what she'd get on sunday teatime) had no Gypsies Tramps & Thieves, Jesse James, Love & Understanding, or One By One. Quite a few ABBA covers.
The finishing run of songs would be decent, but I dunno as it would be one for the ages unless she tweaked it slightly.
