Art dealers from across the country will display their wares in the bedrooms, kitchens and closets of Hollywood's hip Chateau Marmont Hotel at this weekend's fifth annual "Gramercy International Contemporary Art Fair." Designed as a low-budget, high-style affair, the emphasis at this popular event is on cutting-edge art by emerging artists. Visitors can check out the latest trends in art while purchasing an original artwork for quite a bit less than say, Vincent Van Gogh's recently auctioned self-portrait.

Like most singers, Frank Sinatra Jr. has been influenced by his distinguished father. Unlike most singers, Sinatra Jr. spent time as his father's musical director, learning the music inside out. You'll spot more than a few similarities to Ol' Blue Eyes when his son takes the mike in front of a 20-piece band in this fund-raiser for the Malibu Optimist Club's youth programs. Also on the bill: the Dixie Dandies.
