I'm normally up before 5, often before 4. It's just my normal biorhythm, and one of the reasons I gave up music as a full-time job. (Only preemptive naps and coffee allow me to stay standing through a Saturday night gig.)
I've never understood why we need to "save" daylight in summer, which in northern latitudes is in plentiful supply. It's annoying when the sun's still out past bedtime.
