After splitting with Messina in the late '70s, Loggins was surprised to find himself in small clubs, struggling as a solo performer. Opening up for Fleetwood Mac during their turbulent, but hugely successful tours, was a break. Plus he met and befriended Stevie Nicks, who sang on his first solo hit, "Whenever I Call You Friend."
Instead of flying Nicks in for one song at each tour stop, Loggins said he splits her part between the singing members of his four-piece traveling band.

Yeah, as if he could get her involved in ANY of his show since 1979 would be a miracle!!!
