The band's original line-up included legendary Taranaki musician Wayne Mason who played the piano and co-wrote one of the band's most popular songs Hands of My Heart with Saunders.
A four-piece for many years now, the current Warratahs line-up is Nik Brown (violin and mandolin), Mike Knapp (drums), Nick Theobold (bass and vocals) with Saunders on guitar, harmonica and vocals.
Saunders says country music was not so cool when the Warratahs began so it was gratifying to grow a large following that included people who had not been previous fans of the genre.
"I'm amazed that I meet so many people who saw us play at the Cricketers in the 80s because it never seemed like the audiences were that big."
As well as continuing to write, record and tour with the Warratahs during the past three decades, Saunders has released solo recordings and in recent years he has worked on a number of collaborations with the new breed of country artists.
"I have just finished recording with Delaney Davidson and it has been great performing live with him, Tami Neilson, The Eastern and Marlon Williams in recent times.
"Tami and The Eastern have performed covers of my songs and I loved what they did with them."
Saunders says a Whanganui audience can expect to hear songs from the Warratahs vast songbook, favourite covers and a brand new song Fast Train.
