Shows that were considerably changed after their Broadway run

Are there many shows that were considerably re-written (mostly really speaking of the material itself rather than any fiascos like the recent Shrek tour) after their Broadway run? The Addams Family comes to my mind.

I'm asking because I think if the authors of Lempicka rewrote some scenes and lowered some of that insane belting, they could have a nice show that'd get performed at drama schools or ambitious regional theatres. Not sure if it'd get licensed a lot outside of these?

Or are most shows that don't work just abandoned to find more money elsewhere?

Merrily (to name an obvious one)

Almost Famous did a post-Broadway workshop at the O'Neill but I don't know how substantial the rewrite was.

Jagged Little Pill had some, right? (some of which were done during the Broadway run)

Seussical was scaled down.
Bat Boy and Heathers swapped out new songs for their London productions.

The Scarlet Pimpernel and its 897 versions.

Grease

Chess

Rocky Horror ( has now just descended into over the top camp )

Follies has been tinkered with quite a bit since its original Broadway incarnation. Most notably its original West End production saw several songs replaced and some pretty significant book changes

The shrinking of Les Miz. Lion King dropped some stuff in the last decade I think.

Chess was changed FOR Broadway, not after it... right? It just reverted back to the original West End version after that, or is it now a blend of the two? It

When Mean Girls was about to bring in their next cast in 2020 after the OG leads left, they did rework a lot of the show. Moments when Cady addressed the audience (like the voiceovers in the movie) were removed. Certain lines were changed. I have a feeling that will carry over to the West End production.

Rentaholic2 said: "Amelie was significantly reworked for its UK premiere, and I believe that is the version of the show that is now licensed. The score was modified quite significantly and largely re-orchestrated, and I think it's just wonderful. I haven't seen the show, but just by comparing thecast albums, it seems they really cracked the code on it in London. It would be great if the show one day got another chance in New York with the revised version."



The licensed version uses the rewrites from the UK production, but retains the Broadway orchestration.

I agree, the UK production is like a whole new show, it's gorgeous.
