Hi there
About two weeks ago I requested help in identifying a disco song that I heard while at work. Today I heard the same song and can give a bit more detail about the song. Unfortunately I didn't really hear much more of the lyrics, but I misheard the lyrics from the first time, they go "My world is built around you / No one else but you".

The song is a duet between a man and woman. It sounds like it's from the late 70's. It begins with a drum solo, and had several drum solos through the course of the song, it was about 6-ish minutes in length. The song has typical disco strings typical of the era, and a xylophone or vibraphone (or even bell, couldn't quite tell) but it was prominent. Also repeated a distinct pattern of descending half-tone notes at several points.

I hope this is enough information for someone to identify this song. It's driving me crazy and for the sake of my sanity I hope someone can help ID it for me.

Many thanks,
