I can match one thing done with another thing undone.
Where Desperados are drunk
The customers are sober
Where the stack of logs is untouched by fire
The candles flicker with a hint of --
Where the waitresses wear red and black
The sombreros stay fixed to the walls
Where loud piped music blares
Guitars --- ?
'blares' is a bit obvious but what is the alternative? Candles always flicker so I'm not happy with that either. But I am satisfied that I've got a shape to what i want to write and it probably won't be much longer than this. Maybe another two lines.
