 The siege guns have been pounding all through the night

 As I returned across the fields I'd known
 I recognized the walls that I once made
 I had to stop in my tracks for fear

 Play riff #1 on these two lines

 Then I went off to fight some battle
 That I'd invented inside my head


 Play riff #2 on these two lines

 Away so long for years and years
 You probably thought or even wished that I was dead


 Play riff #3 for these three lines

 While the armies all are sleeping
 Beneath the tattered flag we made
 I had to stop in my tracks for fear

 A sentence you seem prepared to pay

 We walked through it's streets this afternoon

 As I returned across the lands I'd known
 I recognized the fields where I'd once played
 I had to stop in my tracks fear
