Thats sad. I just saw him at celebration, he wasn't looking too good then.
His dedication to fans is to be commended.
And lets not forget he really did give R2 the personality that we all love, not easy when you're cooped up in a big tin!!
That one part brought so much happiness to the world. He made R2 alive and forever legend. Thank you Kenny Baker. Rest in peace and God bless your soul for the happiness you gave.
