Streetdance

Dear all,

Through my discography I received the following e-mail from Byron Canney:

Hello,  I pulled-up your website in the hopes of locating an album that I
had in the seventies...I believe was entitled "Streetsong" (may be two
words) by John Cage.  It was delightful, and full of improvisational sounds
(including the glockenspiel as I recall), childrens singing as part of it,
and perhaps German in recording (the title may have been in German too).  I
cannot find even a hint that there ever was such a piece.  Is it possible
that you can help me locate this, or even confirm that John Cage composed
this montage of songs by this title?

Thank you,

Byron Canney  (byroncanney <at> aol.com)

I haven't got a clue what this is, maybe someone else has heard about it???
Thanks and best,
Andre Chaudron
