Fred Dagg was an extremely influential political and cultural commentator in the NZ of the 1970s (before it became NZ/Aotearoa).
His name is associated with the agronomist Bruce Bayliss and his 7 sons, the Trevs. (All named Trevor, from the Welsh name Trefor).
He was noted for not only the spoken word but also music, such as "We Don't Know How Lucky We Are" and "Gumboots".
It is believed Dagg is still alive, but his influence has waned and Kiwis now look to Lorde (16 years old) for cultural guidance.
For non-Australasians, the name is clearly derived from the Ozspeak "daggy", meaning grotty, of low value.
