Hmm... PB isn't that hard. Just read the chords and play the parts that aren't the vocal parts. Worked well for me. As for ATM, I played something different for "Making my way downtown, walking fast..." too.
I play :
RH : B, A#, F#, G# twice
Instead of going down to E on the last note. *shrug* It sounds better, the second time, you do what they say.
