I used to listen to 710 AM-WDSM in Duluth in the 1980s on my '77 Chevy pickup's Delco radio and took delight when the Bobby Aro's polka show was broadcast on Saturday evenings around 6pm(?). My Highway 7 was more likely to be Highway 4 and my companions and I got to know a fair few taverns in rural Saint Louis County as we travelled back to Duluth from a day's gunning or a weekend at the deer shack. I never forgot King of the Great North Woods. Bobby Aro and those outings fit like a hand in a glove and what memories they are. Thank you for posting. I watched and enjoyed the interviews, clips and, of course, Bobby's music.
