You're the top! You're the coliseum! You're the top! You're the Louvre Museum!
You're a melody from a symphony by Strauss,
You're a Bendel bonnet, a Shakespeare sonnet, you're Mickey Mouse.
You're the Nile, you're the Tower of Pisa, you're the smile on the Mona Lisa;
I'm a worthless check, a total wreck, a flop,
But if baby, I'm the bottom, you're the top!

Another version, is a joyous delightful duet with Kate Smith(?)
(from the CD Suddenly It's Spring)
[ Lyrics from: http://www.lyricsfreak.com/f/frank+sinatra/youre+the+top_20354840.html ]
[You're the top! You're the coliseum! You're the top! You're the Louvre Museum!]
You're a melody from a symphony by Strauss,
You're a Bendel bonnet, a Shakespeare sonnet, [you're Mickey Mouse!]
[You're the Nile, you're the Tower of Pisa], you're the smile on the Mona Lisa;
[I'm a worthless check], a total wreck, [a flop],
<But if baby, I'm the bottom, you're the top!>
[You're the top! You're Mahatma Gandhi!]
You're the top! You're Napoleon Brandy!
[You're the purple light of a summer night in Spain!]
[You're the National Gallery, you're Crosby's salary!]
You're cellophane! You're sublime, you're a turkey dinner!
[You're the time of the Derby winner!]
I'm a toy balloon that's fated soon to pop!
[But if baby, I'm the bottom] no, if baby, I'm the bottom,
<But if baby I'm the bottom, you're the top!>
