"The Naughty Lady Of Shady Lane"

I admit I cannot sing a note, but when the Aames Brothers start harmonizing into the title , I cannot help but try to sing along with the highest of the three brothers.

Does anyone know of a program whereby I can learn to sing without offending my next door neighbors or my Pretty Pammy who is trying to take a shower in the same space as I am trying to sing in?

Thanks
