mrs. z~(trivia item: in canada, where i'm from, that's pronounced "mrs. zed").
when we do 'another train' at song circle, i sing the verses, and the group sings only on the choruses. people just improvize harmonies that sound nice with the melody of the chorus.
the instrumental accompaniments jeff and i just play 'by ear', which is quite something, considering i spent most of my musical life playing classical music from notes on a music stand.
i borrowed a tape of pete morton from a friend of mine, who found it in a store here in toronto called The Country Music Store. it might be available by mailorder over the net from somewhere....
