I agree with T-block for the first time

But l;et me add this to the mix
pay real close attention to the intro
learn it first
why?
one it will really identify the song and they will know exactly what your are playing
two the intro is usually some hard to hear part in the middle of the song with all kinds of business going on and its hard to hear but if you catch it on the intro when you get to that part in the song you already know how to play it
third intros can be adapted to other songs
and you can make vamps out of them
lastly intros usually have runs that you can begin to add to your bag of tricks
so learn those intros you will be happy you did
first mpressions are lasting
if you start the song like the record people will be more inclined to believe you know how to play the song and it becomes easier to teach them
singers can be rough on newbies
i still have the bruises on my ego to prove it
