Fred the Swede is a musician who played with Alex Horne in his band, The Horne Section. He was later called up to do a few appearances in Horne's new show, Taskmaster, but he had gone back to Sweden in 2017, where he is supposedly in his own band, so he may not be coming back to the show physically. His father is a painter/decorator, which he took up along with his music.
Of course, music is Fred's passion. His favorite foods are hamburgers, boiled potatoes, cream sauce, fried onions, and lingonberries. He is rather "amiable" with Doc Brown, which is short-lived in the task, 'Get information from a Swedish person, who may not communicate in English'. Fred is afraid of failure.
