I'm trying to pin Chris Noth down on some dates, and he's not helping.

"The older you get," he said, "the years just start running together."

In fairness, it's not merely age. The topic of our interview is Natty Scratch, the band Noth co-founded that will be celebrating 43 years of existence this weekend with a pair of shows featuring all the group's original members - and people who've joined over the years.

The band's current lineup includes founding members Noth (guitar and vocals), Tommy Langford (bass and vocals), and Steve Cooley (percussion and vocals). Keyboardist Rick Stoneking joined in the early 1980s to replace Noth (who joined several touring bands), and drummer/vocalist Richie Reeves has only been with Natty Scratch for about a decade.

For this weekend's concerts, the group will also feature original drummer D.L. Blackman (who cut back on performing, making way for Reeves) and - returning from Alaska - guitarist/singer/co-founder Pat Ryan. (Noth said he's not sure when Ryan left the Quad Cities, except that it was before his own return in 1991.)
