CATS has got to be my all-time favourite (even though it ended before I was born, my mum bought a video biggrin ), so much so that I even did a dance in school based on it. We got to wear fur and it was so fun! We got a really good grade for it too xd "Jellicle Songs for Jellicle Cats" is the best song.
Rent is my favourite musical at the moment though. I love the songs "Seasons of Love" and "La Vie Boheme" and "Out Tonight", aw shucks, I love them all heart
I haven't seen Avenue Q but it was playing on Broadway when I went there. We had to go see Chicago instead cause it was too expensive crying I REALLY wanted to see it though.
