Here's another tribute video featuring some samples of great performances by one of my favorite silent film era stars and a real pioneer in the industry: Luke the dog. Luke appeared in a number of early silent comedies due to the fact that his owners - Roscoe (Fatty) Arbuckle and his wife Minta Durfee - both worked at the Keystone Studio.
The music is "Aw You Dog!" performed by Cab Calloway.

For those who have asked, in my opinion the best place to find more of Luke is on the excellent DVD set "The Forgotten Films of Roscoe Arbuckle". (less info)
