What is funny, Toto played lots of session work, movies sound tracks , commercials and other people's records on the side, like the old " Wrecking Crew " of the 1960's and early 1970's.Even buried among late 70s and early 80s pop rock something about their musicianship always stood out. Once I learned who the players were it was obvious why they sounded different. Great musicians.
