I play a bit of harmonica. It's definately in the key of D. Jeff also has his guitar in Drop D tuning. Just listen to the recording (IATTBYH DVD) and you can pick it out. Okay...got my harmonica. Goes from (holes) 5 to 6 blowing out, then suck in and bend twice on 5 and blow out (sounds like wah-oo-wah hoo for the bend part). Then bend in and blow out on 5 (wee hoo). Then in on 4 and back out. Now suck in and bend twice on 4 and blow out, following the same progression from 5 to 4, but this time go from 4 to 3. If you play around with that, hopefully you can get an idea. Hope this he
