I should have given you a shout earlier, but figured this could not be too much of a problem to sort out. The trick is in holding your hand above your head to represent a shower head while dancing and singing.
I drove all round Wilkoppies yesterday looking for a 12M HDMI cable, currently using a 5M cable but that is too short. Scoop sells them for about half the price of anyone else but I think they're probably closed till next week, no reply to my email enquiry yet.
