... covering Lulus' "To sir, with love" and there's a big, chiming chord - probably a stratocaster - in the middle of the intro section which I think I've worked out as an F6sus4; it sounds right on guitar and even on the keyboard so it's gotta be close...

For those who like to play with this sort of thing, it is XX3031, or F, G, D, F.... and is hit quite firmly over the four strings with an angled pick for best effect...

Anyone care to play this game with me? :-)
