The much under-rated (imo) Long John Baldry. A bit of boogie woogie.

Glad I logged in when I got up for a drink of water (made a cup of tea actually).
I too think LJB is great. He used to gig at the Bromley Court Hotel when I was a child. My parents & some cousins went to see him and used to talk about him. We had the record, "Let the Heartaches Begin". Not sure that he was underrated, he was certainly highly regarded in the music industry, just not a big recording artist.
