In the item on N.N.B.?s "Slack" in this week?s "Minnesota?s 50 Greatest Hits," Wayne Hasti was credited with playing bass. Actually Rusty Jones, the group?s original four-stringer, played bass on the recording. Hasti, N.N.B.?s third but not final bassist, joined the band later. We regret the error. Jones himself wrote in with some history and notes about a few Minnesota faves from the early '70s. Here's his letter.
