Xmas at KMart

Foster MacKenzie III, a.k.a. The Duke of Puke, a.k.a. Root Boy recorded in 1978 as Root Boy Slim & The Sex Change Band with The Rootettes his pretty obscure and remarkable Christmas track 'Xmas at KMart'.
This self-produced ironic recording was the starting point of his career, as an A&R manager of Warner Brothers heard it and offered him a record deal immediately. They made six more albums after this one. Root Boy Slim (born 1945, died 1993), who started as a singer-songwriter, soon gathered instant cult-fame with his mixture of glamrock, Memphis-style boogie and blues, but died way too soon at the age of 48 of natural causes.
