Have 2 kids at HG.
Music is taught following the national curriculum but the school also pairs up with Wandsworth council and organises choir for kids at both ks1 and ks2, small singing groups, band club. In yr 5 they participate to a music event at the Royal festival hall where they sing with a number of other schools in the Council. In addition an instrument (clarinet) is taught in yr4 and they offer the opportunity to continue in yr5 and yr6.
As for sports, the PE teacher is passionate about her job and would involve all kids in any possible activity if they wish.
They have usual sports for primary and they have tournaments in ks2 for netball, football, rugby for selected kids. They have a successful swimming squad and selected kids in gymnastics.
All sort of sports clubs are offered in the morning and afternoon. Running,
Netball and hockey, rounders, tennis, football.
Hope it helps
