If Rusty truly retired that's the end of Poco anyway. He's been the only legacy member of the band remaining and it's just not Poco without Rusty's steel. I saw them for the very first time around 1970 when they opened for The Guess Who and they tore the place up. I felt bad for The Guess Who because there was no way to follow that opening. Their energy and performing skills just topped anything I'd ever seen up to that point in time. Some years ago the band I was with had the privilege or opening for them and I had a chance to meet and talk with Paul and Rusty. In fact Rusty sat and had dinner with me and their former record producer Jim Mason. They're a great band a really enjoyable to talk with. Not your average "rock stars". Very down to earth guys.
