I'm trying to find a song that I had on a compilation cassette I made many years ago - probably from vinyl LPs. It was probably from the 1930s by an old African-American singing group with female singers and a lead male singer with a deep voice and it was about a wedding that was about to happen. Some of the lyrics were something along the lines of "Look out preacher, they're comin' in, this here weddin' is about to begin." I have searched on Google without success. Help anyone? This is very obscure!
