Leaving party ideas- please help!?

i'm moving a couple of hundred miles away in may so i'm having a leaving party at a loacal hall, instead of tacky disco lights i'm gonna have fairy lights dotted around the place and instead of a dj just a good sound system and cds that i've made with my favourite songs on, but what should my theme be? what food? what drink? what entertainment? and any other ideas? thank you !!
