When tickets went on sale this past spring for the Rod Stewart/Stevie Nicks July 28 "Heart and Soul" show at Pittsburgh's Consol Energy Center, I took pause. I've adored Rod since his earliest days in the music biz, when he sang his heart out with Brit bands like Long John Baldry's Hoochie Coochie Men, The Jeff Beck Group and The Faces. But as much as I love Rod The Former Mod, was I really willing to fork over $150 to sit half a mile from the stage of a 19,000-seat arena to hear him sing "Do Ya Think I'm Sexy" from his sad disco days, or croon old standards with faded gypsy queen, Stevie Nicks? No, I decided to spend my concert cash to see another vocally endowed white boy who also performed here last night: "Southside" Johnny Lyon. Johnny brought his 7-piece Asbury Jukes band to the Palace Theater in the small town of Greensburg, PA, and delivered his usual rousing show. He's been performing since the mid-1970s and is considered a pioneer of the famous Jersey Shore sound that emerged when Bruce Springsteen put Asbury Park on the musical map 40 years ago.I've long considered Johnny Lyon to be the finest white rock-soul singer in America.
