It's all good, man
I don't remember Walker's crisps at all from when I was a kid. It was Golden Wonder or Smiths or KP. Or cheapo versions like Bobby's.
Bobby's salt and vinegar spirals were excellent. Not as good as the original Smiths Twists, though.
And Salt & Vinegar were always blue, apart from Walkers', which were always green.
