My fav way to learn a cover isn't from the record .
The fun way is to get the acoustic out and thrash through the bits you remember between you all and that's it.
Chances are you have forgot the boring middle 8 or the change no one remembers .
If sad muso's can't remember a bit ,jo shmo in the boozer can't .
He just wants the catchy bit any way .
God I know some of you guys will get chest pains reading this , it's just another way of learning them .
I've done the less fun way to lol
My motto for covers " quick to the catchy bit "
