I'll chime in a little more
It was a different world - vinyl, 8 Tracks in the car, no interwebs, no cable TV (until 80s)
Jaco lived on NW 17th Way in Fort Lauderdale through most of his 'famous' years. There were several excellent jazz players living on the same street - duplexs & apartments
I can remember eating green pea soup for breakfast outside on a table about midday (everyone played & stayed up all night sleeping late) - he was in good form - healthy and excited by his success - probably right around 1979 - 1980
Most folks were in awe, some very close personally to him. I said something to the effect of 'you know Jaco, you have a responsibility to all those players who look up to you' (I meant to set a good example) - I've always thought his response was telling - he didn't like or accept this idea
He didn't want to be an idol, I don't think he was ever comfortable with the 'celebrity' aspect of things. He was a Showman and understood the value of theatrics on stage but IMO he never adapted to being 'Jaco' - he tried to play it down but I think it weighed on him
You also have to remember he was a big name but only in certain circles (jazz/fusion) which even then wasn't a huge market - he was voted Downbeat electric bassist of the year several years in a row but the big $$ were not there like pop artists make. In order to do well he had to tour which can be a hard life
During his life, as now, great jazz artists are more popular outside the U.S. - he is still adored in Japan for instance - he was not a household name in his day - some say the early demise leaves these folks larger than life - think Janus, Morrison, Jimi, et.al. - not that they don't deserve the recognition but that WE tend to lionize them
BTW, there is now a JP Park in Oakland Park FL not far from where his ponytail was severed by a train and he was beat into coma. Not much there yet but a youth center is proposed and needed for that 'hood - he lived and died on the wrong side of the tracks
my 2 cents
