"I Won't Last A Day Without You" has been performed by many big names such as Diana Ross, Barbara Streisand, Andy Williams and Ronan Keating, however the popular version everyone knows is by The Carpenters. Anything sung by Karen Carpenter always gets my vote :)

Day after day I must face a world of strangers
C D E B - B E F ^C ^C
Where I don't belong, I'm not that strong
G G A G G G G - F F E E D
It's nice to know that there's someone I can turn to
C D E - B B E F - ^C ^C
Who will always care, you're always there...
^C ^D ^E ^E-^E ^E-^D ^E ^C-A-C^
When there's no getting over that rainbow

When my smallest of dreams won't come true
^E ^F ^G ^G ^G ^G - ^F ^G ^E ^C A ^C
I can take all the madness the world has to give
A ^C ^F ^E ^C G F - G G
But I won't last a day without you!
