Successful solo artist Seth Haapu is another young Whanganui talent Common recalls well.
"Seth is actually a Rockquest judge on the East Coast now and I think he moved to Rotorua with his family the year after he competed in Whanganui," says Common.
"Then, of course, there is Michael Franklin-Browne of Head Like a Hole.
"I think that was back in 1991."
Wanganui Collegiate band Kate in the Lemon Tree were national winners in 1994.
Franklin-Browne, now a music tutor at UCOL Whanganui, has been mentoring 2018 Whanganui Rockquest hopefuls along with fellow tutors Lizzie de Vegt, Sacha Keating and Andrew Condon.
Other memorable Whanganui contestants are 2005 regional winners Legions of Sound.
"Whanganui does seem to breed great musical talent and I love the opera house - it's a fantastic venue."
Common says there is a record number of Whanganui entrants this year and he expects the evening might run late.
"We usually finish the night at 9.30 but I suspect it might go until about 10 because it looks like there may be up to 20 entrants."
He does not recall there being such a high number before and says he looks forward to seeing the talent.
