Here's the link for the following diary entry concerning the concert by The Police in Tuskaloosa's Bama Theater on Saturday, October 13, 1979. It is my opinion that this cat got a little mixed up in his diary and what he's talking about is that they arrived in Tuscaloosa on Saturday, October 13, 1979 after the state store had closed so they were facing "No Liquor" on Sunday which made 'em send a roadie to Pickens County or Columbus for liquor.

Saturday,October 13 Tuscaloosa, Bama Theater

This is an unnacceptable state of affairs for the Hotrods, and Meaty the roadie is promptly dispatched to drive over the nearest border point to stock up on Jim Beam etc. Manages to make it back literally minutes before showtime much to our relief. Took him 5 hours..."
