I found this ABC on TheSession, and I wanted to convert it on the converter of concertina.net, but I couldn’t, because it says that it has an error (or maybe more than one).
I don’t read ABC, so, if someone can correct those errors to be able to get the sheet music, I’d be so grateful.
Here it’s the ABC as found on TheSession:
