What song does Turk lip sync in scrubs?

Turk lip syncs to "All By Myself" in Scrubs, and it’s such a classic moment! Every time I hear that song, I can't help but think of him belting it out.

I've downloaded many versions of "All By Myself" in MP3 using TuneCable BeatOne.

But according to some comments“ The song he lip syncs to is "Guy Love" – but here's the twist, it's not an actual song; it's a parody of a song created specifically for the show. However, the tune is based on "Islands in the Stream" by Kenny Rogers and Dolly Parton, which is a classic duet.”
