A lot has happened since Rod Stewart appeared on "Good Morning America" in 2003.
He turned 60, won his first Grammy, got engaged, is expecting his seventh child and was awarded a star on the Hollywood walk of fame.
Stewart was in the studio on Monday to perform from his newly released album in the Great American Songbook series, "Thanks for the Memory: Great American Songbook, Volume IV."
"I feel pretty good," Stewart said. "The kids keep me very youthful and so does my gorgeous fianceé."
Stewart proposed to former British model Penny Lancaster, 34, atop the Eiffel Tower on March 9. He has six other children by four women, ranging from age 10 to 41.
Stewart performed "Blue Skies" for the studio audience. The classic was written by Irving Berlin and originally made popular by Bing Crosby.
Stewart's new CD features duets with Elton John, Chaka Khan, Diana Ross and others. To date, the first three albums have sold a combined 12 million copies in the United States. Stewart said volume 4 is the last in the series, and all four will be released in a box set on Nov. 15.
