I used to teach dance at the first Adelaide Arthur Murray's studios when it first opened in a basement along the Currie St end of Gilbert Street in the 70s. Not sure what the basement is now!

Thanks for that. It would have been at 31 Gilbert Place, one door south of where Infinity Games is now. http://adelaidediscoscene.blogspot.com.au/2009/04/arthur-murrays-dance-studio-gilbert.html
