What Makes You Smile?

I'm walking the dog up 1st Avenue this afternoon.  Without seeing anyone, I hear a person singing in a loud/bad Liverpudlian accent "and I'm happy just to dance with you".  I then see a white haired man wearing knee socks, camouflage shorts and a Chicago T-shirt walking past me.  The T-shirt commemorated the band's 1989 tour.   He was thoroughly enjoying his walk and the music.
