To the two obsessed Moulin Rouge fans at the Alfresco Film Festo.
You totally annoyed everyone within earshot by singing every breath of every song.
If that wasn't annoying enough, you also said all the lines a few seconds before the actors did! It's clear that you've seen this movie waaay to many times.
Grow up and get some consideration for other people.
BTW - You both can't sing.
