The chorus of "Brief Candles" is:
|: A major | A major 7 | D major | F major | E major :|
D major | A major
D major | B major
The verse of "This Will Be Our Year" is:
A major | C# minor | A major 7 | D major
F major | E major | D major | A major
All but a few of the chords in the chorus of "Brief Candles" are held for a full measure, but the chords in the verse of "This Will Be Our Year" are each held for half a measure.
The bass parts for these two sections play a similar descending line. Simplified, it's something like A (G#) G F# F E D A. "This Will Be Our Year" has that G# (under C# minor); "Brief Candles" doesn't. The bass part in "Brief Candles" also goes on a bit longer (under D major and B major).
These two sections are different enough that they're distinct but similar enough to lend some cohesion to the songs on Odessey and Oracle. It's worth noting that both were written by Chris White.
