I just figured out some flute parts in "I'm Waiting for the Day," and I discovered that a couple sections in the flute part have the same rhythm as some sections of the timpani.  Here's the flute part at the beginning (~0:05), which is also repeated over and over again in the coda:

Here's the flute part at ~1:09:

I might be missing some sections, but the timpani follow this same rhythm at the very beginning, throughout the second verse, and in the coda.
