The Man With All The Toys

I think he used to sing and play the piano or something like that. I gathered all his toys. What was his name and what fast food is it incorporated? I forgot.

McDonald's A ... It's Mac Tonite. His name was Mac. I loved this ad.

He played piano and sang to the tune of Frank Sinatra, I think it was.

Mickey D

I remember him, but his name escapes me. I can come back with the answer.
