That's a word I usually try very hard to avoid; in part because of the general overuse that's robbed it of any intrinsic meaning, but also because its etymological origins are more unkind – back in the 13th century, it meant foolish, ignorant, frivolous or weak—none of which apply to Jon Long. Unless by "weak" you’re referring to the nerve damage in his left arm that means he's "partially disabled". He can still play guitar, though: and so accompanies himself through a succession of songs – although musical deviations from the chat that weaves around them is perhaps a better description.
