The intro lick lasts a total of four bars - and starts on the second beat of the first of those bars. You could have your drummer count off one or two full bars before you come in.

The tricky part is that the lick comes in on 2 instead of 1. So if you had your drummer click his sticks for one bar out front to start the song, he would click 5 times - then you would start the lick.

Hope this helps!!
