"God Gave Rock and Roll to You"

This morning I listened to In Deep.  Among some other things (about which I hope to have a post to-morrow), I noticed that there's a glockenspiel in "God Gave Rock and Roll to You."  I'd completely missed that before.  It's only four notes, so I thought I could figure those out.  But then I also got the bass part and - surprising myself - the guitar part for almost all of the introduction:

I can't play the guitar part accurately in tempo yet (I learned it just to-day), so I left out the tremolo part.  I tried to overdub that on a second track, but it didn't seem to work.

The song is mostly in D major, but there are some weird accidentals so that one section of the bass part has the same intervals as the glockenspiel part.

The glockenspiel part consists of the notes F#, G, A, and A#:

In one section of the bass part, there's a string of notes (B, C, D, D#) with the same intervals:

It's a half-step, a whole step, and then an-other half-step.  The phrases aren't played in the same rhythm (I just put all of the notes in one measure to save space), but because they have the same intervals, it gives a bit of cohesion to the song.
