I wouldn't be interested either.
You can type "Northern Live" into youtube and see some of their performances. The Snake, The Night, I'm on my way, Do I Love You, etc. They seem to attract a good size audience. However, based on the youtube vid's, you can make your own mind up if they would be in the running for the title of "THE BEST".
Also, a bit of an eyeopener if you type "Northern Soul Band" into yourtube to see who they would be up against! There seem to be a number of others having a go at it.
