This really made my day... had to watch it twice! Really hit home how much I base my favourite movie lists on dance sequences! I'm pretty sure I've seen every one (except High School Musical). Am also impressed at how many my boyfriend has avoided!!!
Key missing ones though, in my view - Blues Brothers, High Society, and Centre Stage :)
I'm up late for UK time because I'm sore between hospital appointments... this really cheered me up, thanks!
