It sounds to me like the word is "work," not luck.
3) I am just a poor boy Work's my middle name If money was a reason/Well, I would not be the same
4) I'll stand up and be counted I'll face up to the truth I'll walk away from trouble But I can't walk away from you
Chorus and musical interlude
5)I have been to Fort Worth,um hum I have been to Spain I have been too proud to come in out of the rain
6) I have seen the David I've seen the Mona Lisa, too I have heard Doc Watson play the (Columbus?) Stockade Blues
7) Well, I wish I was in Austin in the Chile Parlor bar Drinkin' Maddog Margueritas And not caring where you are
Hope this helps.
