Peter Hammill, the first true punk?

That's a tough call. He was definitely an influence on punk but so was The Velvet Underground, The Stooges and other lesser known bands like Death (the Detroit band), MC5 and even Captain Beefheart!

I've done a bit of research on this but indeed Peter Hammill was and still is a one of a kind musical icon who transcended petty genre distinctions.

I remember coming across Death while looking for Death and being confused AF lol.

Apart from say, H to He Who Am the Only One, I've never been entirely convinced that either VDGG or solo Peter Hamill were conventionally Prog as outlined by any of the definitions available on PA. As also evidenced by King Crimson, the Eclectic label seems a bit of a stretch for any creative association that transcends any such perceived boundaries. The lyrics quoted by the OP are from Nadir's Big Chance from 1975 where Hammill inhabits the persona of prototypical Punk and inarticulate 'yoof' Rikki Nadir so there is some dramatic irony involved i.e. the same realm where theater ponces pretend they can't read a.k.a. white dopes on punk. Of the 11 tracks only about 5 are recognizably Punk in style and there's a danger in conflating anything John Lydon likes as being an endorsement of its Punk credentials. Like Hammill, VDGG and Crimson, Lydon outgrew his formative influences and matured into a discerning and thoughtful artist capable of growing into middle age and beyond producing work that is as relevant to us today as those it was inspired by in 1975

Nadir's Big Chance was recorded in 1974 and released  in early 1975, but I think all or at least most of the songs on it were actually old material, were written in the late 60s, in the early days of VdGG, most before they had recorded anything.

It is a kind of twin album to Fool's Mate.

Iggy Pop would have kicked Hammill's a**. And then probably smeared poor Pete's blood on himself and jumped back onstage.
