Yes, on tuesday, June 13, 1978, voodoo rockabilly avatars The Cramps (in their greatest line-up, Lux Interior and Poison Ivy backed by Nick Knox and Byron Gregory) rolled into the recreation room of California's Napa State Mental Hospital, to play for the residents. Don't ask how this was ever allowed.
This charming but thoroughly odd film from 1970 sees Richard Harris play John Morgan, an eccentric British aristocrat kidnapped by the Sioux in the American Wild West in the early 19th century. Reflecting the liberal concerns of the time, the film is meticulous in its re-creation of Indian customs, particularly the gruesome Sun Vow initiation.
