Early in 1990, Hopkin sang with The Chieftains at the London Palladium in a charity show and later joined them on a tour of the UK.

She continued to do projects of her choosing, working with people such as Julian Colbeck; she wrote the lyrics and performed a song on his CD Back to Bach.
Also, there was Marc Cerrone's The Collector, a stage play/opera, for which she performed two songs on the CD and video.
She worked again with old friends, the guitarist Brian Willoughby and Dave Cousins (of Strawbs) on their CD The Bridge.
She also appeared on a Beatles' tribute album by RAM Pietsch.

In 1996, the Welsh label Sain bought Cambrian's back catalogue and released all of Hopkin's Welsh recordings on a CD called Y Caneuon Cynnar/The Early Recordings, which removed the overdubbed drums found on the Decca recordings.

In 1999, she again joined The Chieftains on their UK tour and, later that year, performed concerts in Scotland with Benny Gallagher and Jim Diamond.
There were also three TV documentaries about her, one each for HTV (1998), BBC Television (1998) and S4C (2000).

She made a guest appearance on The Crocketts' album The Great Brain Robbery, sang the theme song for Billy Connolly's BBC TV series World Tour of England, Ireland and Wales and re-recorded "Those Were The Days" with Robin Williams rapping.
She also appeared in the Sara Sugarman film Very Annie Mary.
