After watching the SNL performance last night, the location was obvious.   
 The low D is played on the E string and it's played on two strings.  
 The first tab up here was close.
 
 This is the way colin played it (with the fuzz it's hard to tell):
 
 A|-9-------9-------8-------7-------|
 E|---101010--101010--101010--101010|
 
 Although playing it the way the first tab had it is fine (i'd love to credit it but the second tab overwrote it):
 
 D|-4-0-0-0-4-0-0-0-3-0-0-0-2-0-0-0-|
 
or even 
 A|-4-------4-------3-------2-------|
 E|---5-5-5---5-5-5---5-5-5---5-5-5-|
