Had to share (few else I know would appreciate!). Listen to the guitar and bass from 4:03 as they swap high/low registers. The bass starts high but switches to low when the guitar solo ascends (at around the 4:19 mark). This is probably simple stuff for most but it just ocurred to me today even though I've been rocking the song for years!

The guitar solo just before the above mention section is also mindblowing!
