To quote Sammy's blog when she left for her transplant: 

all my bags are packed, i'm ready to to
i'm standing here outside your door
i hate to wake you up to say goodby
but the dawn is breakin, it's early morn
the taxi's waitin, he's blowin his horn

so kiss me and smile for me
tell me that you'll wait for me
hold me like you'll  never let me go
'cause i'm leavin on a jet plane
don't know when i'll be back again
oh babe, i couldn't wait to go......
