This week on A Prairie Home Companion, we celebrate summer with another special compilation broadcast. Guy Noir goes undercover at a family picnic, Tom Keith goes cruising on Lake Superior, Bertha's Kitty Boutique offers a special summer camp for cats, and Garrison recalls his days at Camp Scotty. Robin and Linda Williams sing "Green Summertime," Greg Brown sings "Summer Evening" and Maria Jette performs a hot and sultry version of Gershwin's "Summertime" ... It's all coming up on our Dog Days of Summer Show, this weekend.
