I'm learning to play Simple Man and would like to know if it's done with a pick or fingers?  
Tabs I have don't say which.  
I tend to finger pick lots of songs I feel are done with a pick.  
For instance I finger pick the beginning to Sunday Bloody Sunday by U2 simply because it's easier for me.  
Am I cheating?
Gosss they use pick live. If you like the sound of finger picking and it's easier for you then use finger picking. There are a lot of famous guitarists that use finger/hybrid picking on electric it's not cheating it's just different.
