Is it only for flats? I heard Jaco liked to get fried chicken grease on his rounds, though this might be another Jaco urban myth.
It Is.
What I heard/read was that Jaco used to eat fried chicken before shows so that his fingers would be greasy.... But with the number of shows he must've played, I would think he'd get tired of eating fried chicken. Hmmmm.
But yes, I agree with most/all... Just play them - rounds or flats.
