Johnnieblueshoes:

Exquisite extended metaphor, one that is bound to please most but alas not all.

Should be a much-quoted refrain from your latin groove album El Nudo Gordiano:

Dame un poco de holgura: 'Give me some slack'

I am thinking G-Bm-(X3) to Em-A7-C-G...to the chorus G-Am (X 3) to the bridge G-Em-G-Em-Am-C-C7-G and back again.
