When I was playing in a Blues Brothers / Commitments style covers band, Mustang Sally was always great for the 'Ask a member of audience to join the singers' choice - and 'Brown Eyed girl' very popular. ( I hardly dare mention it Roo, but those two also sounded great played on a Telecaster - through a Laney or Fender amp ; so forgive me, for I have sinned :) )
No offence, Derek, but I hate "Mustang Sally" with an absolute passion! :x
It's the Number One song for sweaty, lardy pub-singers/comedians to say "hey, look at me, I've got soul". You can just imagine Freddie Starr or Paul Shane off of Hi-De-Hi dragging it out and mutilating it.
Sorry. 
:lol:
No problem mate ; you have ( quite
spookily ) described our most enthusiastic 'volunteers' to a tee ! :lol:
It was worth it for the one time (at a well funded / staged Corporate function ) - that an absolutely
gorgeous , statuesque, young Afro-Caribean lady in a slinky red silk dress - came forward ( As nearly did the drummer, bassist, Male singer and I at the time :P ) to show how it
should be done ...
I agree that musically and lyrically, it is 'nowt special' - but as you predicted, we kept it in the act as a fun bit of public / shared theatre. Great for providing an 'open mike' with (ahem ) 'Lyrics' wholly sympathetic to, and attainable by, to those suffering from chronic Vodka amnesia.
As the theatrical sorts would say:
" I was giving my public what they wanted dear;
prostituting myself for the good of the greater
ART within me " .... :violin1:
