Machines Song. Improvisation?

[Kevin]

I recently heard this song, from a Len concert in '72 in Tel Aviv. It says on the title (improvisation) but that's just what someone at some point labled it. I'm wondering if it's really true. It sounds like an improvisation... but I've never thought of Len as being an improvisational artist at all. How common are lyrical improvisations to Len shows?

There were often in 1972.

Few of them evolved in the (almost a) song.
