Gary, a huge Rod Stewart fan, is currently being treated for brain cancer. His niece Jenna did everything she could to get through to the star on social media – and her efforts paid off. Stewart was asked if he would perform a song for Gary, one of his dying wishes. Stewart obliged and filmed a very special message for the Gary. Choosing his 1977 hit “You’re in My Heart”, the short a cappella performance ends with Stewart blowing kisses and wishing Gary a Merry Christmas.
