OK, back to the 60's: This '64 Dylan "gorgeous vignette" was released on "Another Side Of Bob Dylan" and rarely performed live by him. He claimed to have had "no idea" what it was about but, according to Paul Williams, it was a profile of a Gypsy girl (hint, hint!) Dylan was involved with at the time. The song was a staple of the pre-fame Byrds' repertoire at Ciro's in West Hollywood and was included in their '65 debut album "Mr. Tambourine Man". Covered by Dion in '78.

Yesterday's answer: "Brand New Key" by Melanie Safka. Who can forget Heather Graham as Roller Girl in "Boogie Nights" - "I NEVER take my roller skates off!". Interesting how divergent Freud's, Adler's and Jung's interpretations of "lock and key" in dreams are! http://www.youtube.com/watch?v=ZIFknAdVvNM
