Blood Brothers is the one. Didn't take long, this one...
Clues explained:
Clue 1: The first line of this song's lyrics contains a metaphor.
(Walk through the) garden of life
Clue 2: A line in the song points to a later album title. Another line in the song has by some been (over)emphasized as a key to the song's theme.
The line "for a second a glimpse of my father I see". The loss of Steve's father has often been cited as the song's theme and inspiration, but if we look at the rest of the lyrics, the "Blood Brothers" image seems to carry a wider meaning than merely the personal father-son link.
