@ Christophe & jacko:
I'm pretty sure Stanley played his standard tuned brown bass on the school days song, so jacko your bassline riff was probably correct Then later on he switched to using his tenor basses for that song exclusively. I think he played the carl thompson piccolo on Quiet Afternoon (and maybe a little riff in Life is Just a Game) but i dont think he even had the tenor bass yet when recording that album.
I saw Return to Forever's last show of the tour, amazing, and I think Stanley was the star of the show. The only thing i actually didn't like was that he didn't go back to a standard EADG bass like he played back in the day- and he stuck with the tenor, which meant a lot of the bass parts i was used to had to be played an octave higher Other than that... incredible!
