What does David Foster have to do with the Paul Simon song 'Bridge Over Troubled Water?'

I wondered that myself when Josh Groban sang it on Great Performances featuring David Foster.

I have found that Foster was producer on Bonnie Tyler's cover of the song, which was written by Paul Simon.

Seems to me like a rather tenuous connection to include the song in this particular collection.

And just as further information, the original Simon & Garfunkel recording (1970) was co-produced by Roy Halee, Paul Simon, and Art Garfunkel.

His father, also named Roy Halee, provided the singing voice for Mighty Mouse in late 1940s Terrytoons cartoons.

Something we all need to know, right?
