It is my guess that this fill was improvised at the end of the tune in which case it makes it very hard to transcribe. In order to transcribe you first need to establish the time against which the particular groove or fill was played. Since Bonham probably just "went for it" at the end of the tune, it is hard to determine where his time is. So what I did was continued the time that was stated in the tune just before the fill occurs and carried it all the way through the fill to the end. When Robert Plant says "time" at the end of his phrase, I used this as beat one of the pick up measure. The first two notes of the fill occur in beat 4 of that measure. At first I had them right on beat 4 but then I listened more and more and it sounded more like they started on the 2nd sixteenth note of beat 4. Now I listen to it again and I want to but them back on the beat again. Like I said....to try and grab the exact placement of a fill that is just started at random is a tricky thing. I listen to this over and over again and I hear the possibility of the placement of some of the notes against the time stated in the song  possibly needing to be adjusted but then after reviewing them again I think they are ok. What is important however is to capture the ideas and the nuances of the drummer and I feel this is done quite accurately. The licks I truly feel are transcribed correctly as far as notation and instrumentation. They are pure Bonham in every aspect. In short...his ideas are captured. The placement of these ideas against a time source may not be accurate but  I believe Bonzo was going for a feel thing at this point in the song and not so worried about playing his lick perfectly in time. Not to say that he couldnt or his time wasnt so great but at this point in the song a focus on time really wasnt needed. Its just a "roll out" at the end of a tune and the rest of the band probably just hit with Bonham on his  cue to end the tune. Normally if I am not 100% sure on a transcription I won't post it. This was a request however and to avoid letting a vistior down, I gave it a shot. If anyone has any suggestions on this transcription please feel free to email me with them. Thanks a lot!!!!
