YOU'RE ALL THE WORLD TO ME key Ab 2:50
2 bar intro and the vocal starts at 9 seconds with the verse "everywhere that beauty glows.. you are....", continue through the verse, hold the last note at 40 seconds then it's a quick 1 bar intro into the main theme from 44 seconds, vocal starts at 46 seconds with the main theme "you're like Paris...", continue through the main theme twice (and there are alternate lyrics for the 2nd time - "you're lake Como when dawn is aglow...."), short piano solo from 2:02 (playing the melody) and the vocal back in at 2:19 with "you're moonlight on a night in Capri...." continue through and finish.
NOTE - the MP3 download and the demo have TRIO in the tag, but it's a Quartet with an acoustic guitar simply providing light strums, very unobtrusive. 

MP3 DEMO:
M3401. YOU'RE ALL THE WORLD TO ME - Ab Quartet
key - Ab - vocal range - Bb to D
The wonderful song from the 1951 film "Royal Wedding" starring Fred Astaire - watch the clip and be amazed at the technological brilliance of the time, and the wonderful dancing!
Same arrangement as M3400 except a full tone lower.
