Hey guys i recently fell in love with Johnny Cash's I've Been Everywhere. I checked out the tab and its looks so easy, but I cant pick up how to strum it. It's hard to figure it out with the piano in it and its so fast that im just like attackin the strings and u cant hear anything words over me strumming. any strumming techniques or any way of playing the song that u guys have found to sound good would be appreciated. thanks.
I always play this rythmn for for most Johnny Cash songs:

boom chicka, boom chicka, boom chicka. Or

1&a 2&a 3&a 4&a
