"Pure unadulterated shite" sounds like a euphemism for "wish I'd thought of it, but didn't have the talent, and probably never will have".

OK - easy to knock it 41 years later if you've got nothing better to do, but it made the artist and a few others a bit of fame and money, stayed in the charts for 16 weeks (four of them at number one)and obviously kept Joe Public happy for a while, or they wouldn't have bought it by the ton. It won the Ivor Novello award, as well, as I remember. Hardly shite.

If it was about anything it was probably about envy and jealousy.
