[SML] swimming pool onstage

[Richard Niederberg]

Dear Duncan,
One of gigs that I worked years ago was the 'Donny and Marie' show, where
they heated a shop-built pool with a very long piece of spiraled Nichrome
wire,right off the roll, hooked directly with 4/0 to a company switch fused
at 400 amps.
