Yes it was a song written during the British Blues Boom of the late 60s. It was by a group called 'The Liverpool Scene', featuring the poet, Adrian Henri(y). I think it may have also been written by him.

I have not got it written down anywhwere, but I will try to bring some more of it from my head. If the whole thing does not appear here shortly.

'Got the Savoy Brown ---- ------ hand me down blues'.

'Got the Jethro Tull ------- ------ belly roll blues'.

Is all I have at the moment.
