To say the musician, from Bury, was bemused would be an understatement.
Although he has achieved modest success, he has never produced any official merch.
“I was completely isolated and living in a caravan whereas a lot of the people wearing this stuff seemed to be having a great time and living a better life than me.
He explained: “I was aware I had some fans in South America, a Chilean radio station recently aired a feature on my last album, which didn’t change my life, and I’d get the odd email from a Bolivian hipster asking me to listen to their tracks.
“Although its logotype may be relatively uninspiring in and of itself, the Boothroyd brand had nailed global ubiquity without trying.
Peter doesn’t believe those wearing the clothing know who he is, which has made the brand’s success all the more surreal.
Using organic cotton and eco-friendly inks, Peter had 100 Boothroyd t-shirts made which he then put up for sale online, targeting the Korean market.
