Ready to play today's Guess Who? It's a daily teaser where we select a now or then photo of a face you may have seen before. The 'Guess Who?' photo is posted every morning at 10 AM EST with just three clues. We then post the answer photo every afternoon at 4PM EST. You can see the rest of them here.
1. He moved to Memphis at the age of 13.
2. He was conscripted into the military in the late 50's.
3. He never received formal music training and learned to play by ear.
