anyway, my main take on sex pistols: boy band or no? is that you have to come up with a consistent set of criteria that a group meets to be considered a boy band, and the pistols were so inconsistent that it’s impossible to see how you could apply it to the without applying it to basically everyone
They were a boy band to the extent The Monkees were a boy band: Both were created by an executive to fit into a fashion and both had actual musical ability. Neither were "True And Honest" bands like Nirvana which formed from webs of friendship and/or want ads.
Were the Sex Pistols a stunt act assembled by promoters? Clearly
Other than being assembled by promoters were they a boy band by any recognizable metric for such? Not by my reckoning
fwiw, my criteria is:
1. plays music written by producers/managers/label
2. public/personal life largely controlled by label (this one is subjective, i know, but important)
3. are part of a marketing strategy to sell items other than music
the pistols only meet 1/3 here
