Bob Welch "Love On The Line"

[Malc]

Greetings to all ... can anyone hekp ?
I'm trying to find out details on a Bob Welch track that appeared on his long-unavailable "Eye Contact" album from 1983. "Love On The Line" (so I've been told) features various members of The Beach Boys on backing vocals, and seeing that I'm an avid collector of said band I'd like to know more.
I have a copy of the track on tape but have no further details.
Composer(s) ?? Producer(s) ?? Which Beach Boys appear ??
Can anyone out there assist ?? Thanks .....
