Billy, with an acoustic guitar, a small amp, an electronic candle, a Latvian lightshow and a bottle of Grouse, told stories, sang songs, made us laugh, made us cry and made us singalong. Sometimes all at the same time. It was inspiring and life affirming. He has an ability to make everyone feel at ease and comfortable despite the slightly odd surroundings. His storytelling and between songs chat is every bit as entertaining as the songs and his ability to just make songs up on the spot while more often than not were complete and utter nonsense there were moments of complete genius.

It is rare in this generated pop culture to find an original uncut diamond, but that is what McCarthy is. So next time you see him playing in the UK, do yourself a favour, grab yourself a ticket and your foot stomping shoes and catch him at one of his gigs. You will not be disappointed.
