Im having a 1960s breakfast/garden party?

what am i going to serve??? i have the decorations down packed - flamingos every where, getting astro turf in and having bozed hedging all around. whilst the theme is 1960s its not all about the hippies - think the ladies man 1961 with jerry lewis. anyone with ideas for food??? i dont want the food to be to heavy and will have some people walking around with platters. was thinking smoothies as people enter in champaign flutes???
