Great things about being blind. Playing carols

My grandfather was very musical.  He wasn't musically trained in any way but he could sing and remember songs and words.  No one else in our family seemed at all musical.  when I came along, and showed musical aptitude from an early age, he started teaching me songs.  I remember folk songs, irish ones early on.  but, I really remember that some of the first ones I learned were christmas carols.  I am playing carols for a seniors christmas party next week and so yesterday, I began practicing them on my keyboard.  As I p played the familiar melodies, I could hear his voice in my head.  It occurred to me then that maybe this is what it is like for a sighted person when they look at photographs.
