It was actually a couple weeks ago, but Karen and I went to The Simon And Garfunkle Story
A band, fronted by S&G somewhat-look-alikes, plays a bunch of their songs and tells some of their story as well. All backed by a mix of still photos and videos on a screen behind them.
I would definitely recommend it, with one caveat: the performers we saw (they have multiple across US and the world) were technically incredible. But they lacked that last emotional grab, that would have made it fantastic.
From the website, not the performance we saw. But very similar....
