I don't have my music in front of me at the moment, but I believe that the part I am referring to is Part B in double beat.
In this part, it is when the snares start playing repeated RLRR paradiddles on the edge and the tenors are playing 22112211 SPOCKRIMSHOT 112211.
The bass part has 2 unison eighth notes, a unison quarter note, and then a 11223344 16th note run. I listened to a 2004 recording and instead of 2 unison 8th notes, it was 4 unison sixteenth notes and then the unison quarter note.
I know this is confusing but I did my best to describe it. Thanks.
