Who sang "let me be your lifeguard" and where can i download it?

I think the first line of this song is "as we walk along the sands of time.." and it's from early 90s or late 80s. It's a soft ballad, similar to " girlfriend" or "love moves" by julia fordham. Been searching for this song for quite some time now. Cant find it in google. Hope some could help me. Thanks! :)
