Sixtiesmania

I apologize, but I don't have any information about an organization named Sixtiesmania. It is possible that Sixtiesmania refers to a tribute band or musical ensemble typically performing music from the 1960s era, given the context of the name. Such groups usually cover a wide range of genres from the decade, including rock and roll, pop, and more, often embodying the spirit and style of bands from that era. However, without specific details or a defined location, I am unable to provide more detailed information. If you have additional context or details, it could help in identifying the organization more accurately.
