All night. That’s why I don’t remember him. I was just a kid in elementary school.
I was in bed.
Later I listened to KSFO’s Comedy hour in the evening with Gene Nelson and then John Gilliland.
His story is interesting - he was the best announcer they had except he was zany and would interrupt or put on crazy audio tapes while the commercial were running. So to keep his job, Russ said he would do the all-nighter which no one wanted and their little problem with his antics, so he could do what he wanted.
*sigh* those were the days...
