Brigid, Good news and bad news. Good news - the song is on the following albums -

NETTLE WINE 1.1 Not Till Tomorrow [5] 1972 1.2 Not Till Tomorrow CD [R17] 1998 2.1 Ralph, Albert & Sydney CD [R14] 1997 3.1 Travelling Man [L3] 1999

Bad news I don't yet have them in my collection, but, I'm working on it. Yes Ralph is one of the GREATS, and much more than "Streets".
