My Dad, just called me into the living room saying..."wasn't this your favorite singer a long time ago?' I ran out and it was Donna Summer with Seal singing "Unbreak My Heart", "Crazy", "On The Radio" and by herself on "Last Dance". She looks like a 30 year old, and sounds better than ever! I was surprised at how well their voices sound together! I would love to hear a duet! By the way...it was on KPBS...and filmed in Vegas with some other singers as well...Michael Bolton, Lara Fabian and others...check it out if U can!
