I thoroughly approve the English crowd singing over the haka war dance.
The All Blacks have somehow claimed the right to perform all around the world a one-sided aggressive start that's supposed to be a level playing field.
Any opposition that tries to level things up, be it the Wallabies crowd singing Waltzing Matilda, or the Welsh or English heartily singing their song, good on them.
Otherwise leave it out altogether.
