French Kiss is the solo debut by former Fleetwood Mac singer/guitarist Bob Welch. The songs, with the exception of "Sentimental Lady", were intended for a projected third album by Welch's previous band, Paris. However, the group fell apart in 1977 before recording could begin. So instead, Welch used these songs for his debut solo album.

The songs were for Welch's other band, Paris. I think the system had difficulty because the substitution of Fleetwood Mac for Paris is a small one and retains the status of both bands
