Popular band, from Ponsonby in Auckland, often in the New Zealand Top 10 in the late 60s. Vocalist Larry Morris later went solo and had six singles on the NZ charts 1969-1983 including The Hunt (1969, #5 NZ) and The Game (1970, #8 NZ)..
Larry’s Rebels were New Zealand’s Animals. Our Paul Revere and the Raiders. The top notch local pop band with bluesy bite, who released a handful of vital discs, and for a brief few years were all over the media, the charts and the nation’s bedroom walls. They were Auckland’s first great homegrown pop band of the modern pop era; hard working and electrifying live. Their cover versions nipped at the heels of the originals.

The Untamed were originally from Worthing, East Sussex, formed in 1956 as The Untamed Four. They were often on BBC-TV and toured in support of major acts but never had a hit. It's Not True was recorded with a reorganised line-up, one of a number of personnel changes over the years with founding member Lindsay Muir staying on into the 70s.

On LP My Generation, 3 December 1965 (in USA as The Who Sings My Generation, 1966). Produced by Shel Talmy.

SAME TITLE BUT NOT THE SAME SONG AS
'IT'S NOT TRUE' BY LARRY'S REBELS.
I'm guessing that some casual observers might have mixed up Ricky Valance with Ritchie Valens whose Donna had been on the UK charts in 1959.
This It's Not True was written by the major US writing partnership of Pomus-Shuman but this UK recording seems to be an original version.
There are other songs entitled It's Not True, including one by Paul McCartney (1986).
