Can someone tell me all the movies used in this year (2009) Academy Awards - "the Musical is back"?

This isn't my own hard work!
I got it off of DarkPhoenixBlood on Youtube and just edited a bit and added the last sentence in brackets. Hope it helps!

The first song till 1:17 is Top Hat, White Tie And Tails, lyrics from Top Hat.
The "singing in the rain" is the song Singing in the Rain from Singing in the Rain.
"Hey big spender" is from Big Spender from Sweet Charity.
All the Marias and the "I just met a girl named Maria" are from Maria from West Side Story, what Beyonce sings after that is the song from Top Hat.
The song from 2:09 to 2:42 is You're the One That I Want from Grease.
"How do you solve a problem like Maria" is from Maria from the Sound of Music.
The song from to 2:46 to 3:00 is All That Jazz from Chicago.
3:00 to 3:22 is Lady Marmalade from Moulin Rouge
(2001).
3:23 to 3:35 is One Night Only from Dreamgirls. 3:36 to 3:46: Main is You Can't Stop the Beat from Hairspray;
Beyonce's part is a line from I Dont Know How to Love Him from Jesus Christ Superstar.
Beyonce's next song is from At Last from the movie Cadillac Records.
Zac Efron and Vanessa Hudgens sing a song from High School Musical 3 called Last Chance.
Dominic Cooper and Amanda Seyfried sing Mamma Mia from Mamma Mia.
Beyonce sings a line from Dont Cry for Me Argentina from Evita.
4:35 to 5:05 is Mammia Mia from Mamma Mia.
5:06 to 5:16 is from Top Hat again.
Beyonce's line is from Over the Rainbow from The Wizard of Oz. [Hugh's line I recognise but I'm not quite sure where it comes from. I think it sounds like a bit in the song in West Side Story that Maria sings when Tony dies!]

No idea about the films they were showing on the screen but the songs are:
'You're The One That I Want'-Grease
'All That Jazz'-Chiacgo
'One Night Only'-Dreamgirls
'You Can't Stop The Beat'-Hairspray
'Last Chance'-High School Musical 3:Senior Year
'Maria'-West Side Story
'Mamma Mia'-Mamma Mia
'Don't Cry For Me Argentina'-Don't know what film!
'Somewhere Over The Rainbow'-Wizard Of Oz

That's the ones I got :] I'm not quite sure that's what you wanted but I hope it helps! lol
