Not recently, but when I was doing K9, there were occasionally commercial producers who'd phone up and say, 'We really want John Leeson because we want your K9 voice,' and I said, 'Well you can't have my K9 voice, it's copyrighted,' so they'd say, 'Well don't worry about, can we have a voice that's so like K9 that people won't know the difference.' I think I obliged on one commercial and that was about it.
