Well, it was titled "On Bass", not "On Bass Guitar" and the presenter herself used bass synths.
I have to say that when I saw the title I (mis)read it as "Drums'n'Bass" anyway, so wasn't surprised at the direction it took.
I think it is pretty much impossible to do a show and cover all of the styles, mention all of the greats in every viewers top-ten, make sure you've listed everyone's favourite model of instrument.
I think the recent drumming mini-series was excellent, but even that was subjective and quite superficial in parts.
For me, I think of Tina Weymouth as the awful playing of Psycho Killer on the OGWT, but some of the stuff on that programme has perhaps made me re-think.
The most amusing/ironic thing about the show for me was the ignorance and arrogance of the punks thinking they'd invented something musically, eg. playing lead bass on a Ric copy, whereas really all they did was put safety pins in their clothes and sugar in their hair (and I remember using safety pins to hold on my school blazer top pocket before punk came along).
