LOVE CHANGES EVERYTHING - I'll go along with your choice, ALWRules
The song was the overture itself for the stage musical ( and purposely did away with the usual orchestral summation of a production's musical highlights) - instead compelling the audience to listen to the prologue and epilogue of the whole musical production.
