You will need a large room for this bash. (Gymnasium or a fellowship hall).
I began about 3 months before time to obtain karaoke cd’s and download fifties music. I did a research on oldies groups…40’s,50’s, and 60’s. I then determined the size of program we wanted. We had a meal first with a stage set up and a good sound system. I then looked each artist upon the internet and got a picture of the way they dressed and looked as well as downloaded the song that the artist will be singing so they could practice. I set up rehersal nights for each performer and I then carefully picked out singers in the church that could sing and even look the part (as much as possible). A couple of artists did lipsynching but 16 artists did karaoke with their voice.
Decorated the room in Fifties style, (items obtained at a party store). Had a dance floor for waltzing with your sweetheart. Had a sing alike (chosen by ticket number from the audience) contest for a particular artist… one male and one female. The audience voted by hand clapping and the winners received a 50 dollar bill. The secret is to get the information out early and spread the word. We had over 200 people show up, we charged 10 per adult, 5.00 for 6 to 12 and under 6 was free. We took pictures (everyone dress the 40’s, 50’s or 60’s look)..we got our church information out to many lost folks as well those looking for a place to worship. And we raised 1,500.00 for a having a night of fun.
