That's why I wrote Yves only needs 2 and put his versions of Teen Town and Donna Lee.
But Yves Carbonne also plays a 12 strings (no octave) fretless bass, so he plays (like I do) whatever he wants or what the music needs at that moment.
It's not lame to say every time someone points out a fiver, sixer or higher "Jaco only needed 4", when he's known to have played a fiver for some time: it's just silly stupid.
