The bass starts at the 1:00 mark. The bass line begins as James Murphy finishes singing a verse, and finishes just as he the next verse. G|---------------------------------| D|------7---7---7---7---7---7---7--| A|---5---55--55--55--55--55--55----| E|---------------------------------| This one line is repeated throughout the whole song. I've listened to this over and over and the vocal queues are all I can come up with as when the bass begins and ends.
