Alex Casey attends the ‘Once in a Lifetime’ curtain-raiser at Christchurch’s One NZ Stadium featuring Six60 and Synthony. This week Christchurch city has been in nothing short of a state of Six60-induced psychosis. Rollickin’ Gelato released a limited edition “Lick60” flavour (Milo, banana cake, white chocolate – “who told you gelato couldn’t fly”), a miniature version of Six60’s famous Castle Street abode popped up at Riverside Market selling empanadas (beef or chicken), and all manner of custom Six60 merchandise has been released.
