Bolan was good, indeed.
However, he modelled himself on Syd Barrett, so much so that he walked into the Pink Floyd management office one day saying he wanted a contract and that he wanted to be like Syd Barrett. There's a piccy of Syd on the cover of 'A Nice Pair' (1975? re-issue of the first two Floyd albums) and just about everyone that sees that piccy (myself included at first) asks why is there a picture of Marc Bolan on a Floyd album?
Then there was 'The Hawkwind Incident'. On Youtube there's a clip of Hawkwind miming to Quark, Strangeness and Charm' on the Bolan show (think that was recorded at Granada TV?) and Dave Brock isn't there, he refused to appear on the show; he hated Bolan because he believed that Bolan had ripped off 'Children of the Sun' and re-arranged it into 'Children of the Revolution'. Result - Bolan made money, Hawkwind didn't.
