Jim, I'm here to express my opinion not to change any one else's, you may think it's pointless but you don't seem to have any problem expressing yours.
Rather than being pointless the opinions shared on this thread have almost inspired me to give McColl's singing another chance because, as some have noted, there are some nice aspects to his voice but I'm not sure I can get past that mechanical-sounding vibrato. It's a vocal technique that some American folk singers employed back in the 50's and 60's and it's sounds unnatural and is an immediate turnoff for me.
