Olivia has frequently been a guest on other artist's albums. On some of the earlier discs her contribution is sometimes minor, for instance Olivia played recorder (but didn't sing) on Hank Marvin and John Farrar's eponymous 1973 album, and provided an ethereal emphasis on the single word Hammerhead in the chorus of James Reyne's song. Cliff Richard, of course, often featured her in a duet in the early days - Olivia is the first female singer he duetted with, in the 1970s when Olivia was a guest on his regular TV show. From the 1990s on Olivia frequently appeared in a duet on guest albums.

Olivia reciprocated with her own album of duets with other artists in 2002, the album (2). We have collated a list of Olivia's duets by song

I have taken a liberal interpretation of 'guest' appearances. I've included some various artists compilation albums where they feature the first release (or CD release) of one of Olivia's songs, like the German renditions of Long Live Love and Banks of the Ohio. These are identified as Various Artists.
