This guitar line is played in most parts throughout the song, if you
listen you can here it playing behing the lead keyboard(I think it's a 
keyboard?). There's only one part where the guitar in Way Back When
is different, and that's during the beginning of the second verse, which
goes like this:

                                             ^(at this point, main riff 
                                               comes back in, playing 
                                               overtop)
