The actor, Isaiah Mustafa, looks and sounds a lot like Rockapella member George Baldi. Look at George.
Sher & Geo
Now back to me...I mean, the Old Spice guy. Mr. Mustafa was on The Ellen Degeneres Show a few weeks ago. Ellen asked him if he remembered the script, and this link shows him doing the entire spiel that he had memorized and done so often with the many, many takes they did to get the commercial just perfect. He doesn't look as much like George there, though.
This link on YouTube is an interview with the ad guys for the commercial. It's about 20 minutes long, so you'll need some time, but it is amazing how, in the world of CGI, most of it was done without that particular technology.
Is it wrong that I would have preferred the tickets to the thing I love (Rockapella, DUH!) to the diamonds?
