Hi! I'm just wondering what the case is with theatre fandoms. If say, a musical was first produced in 2007 and ran until 2008 on Broadway, but then has had a West End run and tours since, but no new material, just new performances, does that count? It's not as if anything has been added to the script/songs etc and the original Broadway cast would be seen as definitive, but there have been new casts since so, I don't know! :)
