In 2001, the HaHarmonics - de Castro's clown choir, inspired by Spike Jones - toured a number of UK cities with a Christmas show called 'Oh Carols!'.
This funny, cheering show - suitable for everyone, everywhere, from church steps to late-night cabarets - aimed to show that clowns can sing inside, outside or inside-out.
The HaHarmonics has also been formed as an end showing to de Castro's two-week workshop 'How To Be A Stupid' (see training page).
'can make you laugh and cry in the same moment, a sign of serious talent.'
