I see Jessica and Vera are looking for quartets on Beatles' songs.
(I am interested in pop music adapted for string quartet)
I argue Jessica has E.Righby; I too am interested in it!!
Now I have some stuff such as Yesterday, Hey Jude and some others
I don't know if possible to exchange by e_Mail; maybe...
