SIR - After reading the letter by David Hornsby (T&A, November 29) on Mary Hopkin's number one hit song, I must correct him.

It was Paul McCartney who not only wrote the song for Mary Hopkin but if it had not been for the Beatles who give her this song and she would never had a hit single!

By the way Mary Hopkin's only hit single ever.
