Mary Hopkin will perform a small part in the movie "Very Annie Mary"

In June Mary Hopkin will be seen on the screen for the first time. She will perform a small part in the movie "Very Annie Mary".

"Very Annie Mary" was filmed in the Garw Valley, and was directed by Sara Sugarman. In 1999 Sara won a Pathe/Orange prize for Screenwriting and the Sundance/NHK production award for Very Annie Mary (formerly known as Pavarotti in Dad's Room), which is due for wide release from 8 June 2001. Very Annie Mary is on at selected London cinemas from 25 May and on general release from 8 June.

But this is also interesting (to me, anyway):

Bert Jansch - Moonshine (Mary Hopkin on backing vocals)

Castle Music has re-released one of the finest albums of Bert Jansch "Moonshine" on CD. This CD contains one track "The First Time Ever I Saw Your Face", with the backing vocals of Mary Hopkin.

Release Date: 26th January 2001 Country: U.K. Catalogue No: Castle Music CMRCD112

Release Date: 13th March 2001 Country: USA Catalogue No: Castle Music America

Moonshine was originally released in 1973 right after Pentangle broke up. Though his solo albums are sometimes inconsistent, if ever there was an essential Bert Jansch album, this is it!

The song selection is outstanding, with Jansch giving impassioned readings of such traditional songs as "Yarrow", "Twa Corbies" and "Rambleaway", as well as a suitably austere version of Dave Goulder's classic "January Man". There is also a completely rewritten melody given to Ewan MacColl's much covered "The First Time Ever I Saw Your Face", with the backing vocals of Mary Hopkin. Jansch contributed several original songs to this album and it is on these that he shines. Included are a spritely "Night Time Blues" and the title track, which has a John Renbourn-like medieval feel to it. The album ends with "Oh My Father," originally released as a single and containing one of Jansch's most fluid instrumental jams at the end.

Jansch's complex and lyrical guitar is given lots of room to move while being backed by a stellar core group of drummer Laurie Allen, Pentangle bassist Danny Thompson (who also produced), Tony Visconti on vocals, percussion and various instruments, and the searing guitar of Gary Boyle. Guest musicians drummer Dave Mattacks, fiddle player Aly Bain, harpist Skaila Kanga, and Ralph McTell on harmonica round out the album's rich and diverse sound.
