Is it because of the meds, or Parkinson's? Also, is that why he doesn't play guitar anymore at concerts?
Meds. Although shaking caused by meds can become permanent, which is essentially as bad as having Parkinsons. Honestly, though, it's been years since I noticed Dan's shaking being so bad that it made people mistakenly think that he was terrified of performing. Has it gotten significantly worse again recently>
Also, I am not aware of him stopping the guitar altogether. He seems to prefer it over piano, and it's likely he'd drop the keyboards first if it were up to him!!!
