It's pretty rare to hear Jaco playing a standard from this era (or at all really, there are few but not many) the original poster claims this was in 1974, two years before his solo album came out, and would put Jaco at 22 years old. It's bootleg quality but pretty good.
It is with the same trio he recorded "Bright Sized Life" with, (metheny and moses) and he of course sounds freaking awesome. Pat does too. Heck, they all do.
This might be at Poo's Pub in Boston perhaps. Don't know.
