No problems. I was lucky to identify some of the unknowns, because I actually heard these songs before, although I suspect Shazam wouldn't have identified them. The only one I couldn't identify, which Shazam failed was the unusual Shadows/Adam And The Ants/Iggy Pop style combo "another neat idea" instrumental, which still remains unknown. Perhaps I'll go to the British Library soon and listen to that show, which has that unknown unusual Shadows/Adam And The Ants/Iggy Pop style combo "another neat idea" instrumental. I got the unknown Welsh language punk tune from help on Twitter, where one of the users identified the U Thant track, after I tweeted help in identifying a Welsh language punk tune. It took I guess 5-10 minutes for someone to identify it. First time I used Twitter to do that. And I was surprised how quickly people there helped with identifying the tune. A good tool for future unknowns in the future, although I have not tested it for the unknown unusual Shadows/Adam And The Ants/Iggy Pop style combo "another neat idea".
I have no problems if you want to wikify any potential John Peel's material from Colin Harper's YouTube channel. However, I can't find anymore JP's material from his channel, which hasn't been wikified since I wikified Stefan Grossman's concert of 1971 and a bit of Blodwyn Pig's material on Peel's show from 1970.
