00:00 Introduction begins with a bass line that continues in a similar manner throughout the song. 
00:11 Guitar enters. The player seems to stumble on the faster part of the melody. 
00:29 Vocals enters. The voices sing in harmony. There are now chord changes more like a pop song of the time might have had. 
00:59 Short interlude and two more phrases of text. Same melody and harmony. 
01:33 New instrumental section. Very active drums. Guitar solo. Bass is frozen on two notes. Notice the punctuated chords by the rhythm guitar behind the solo. 
01:39 From this time on the music is static. The guitars improvise, but the bass stays on the same two notes until the chorus returns. The drummer is very active, filling into every new phrase. 
02:21 Back to the chorus. Vocal harmony. Chord changes return. 
02:51 Interlude. 
02:58 Guitar melody returns (like the introduction). 
03:22 Ending. This texture is very improvisatory. 
03:35 End.
