The singer is this dude, who wowed a Tea Party gathering by singing the usually-never-heard third and fourth verses of The Star Spangled Banner. He’s even wearing the same shirt, which I guess is iconic now, since this was all over the Wingernet. It was a Big Fucking Deal back on June 6th.
Obviously, Barber is trying to burnish his TP cred by packing his videos with high-profile guest stars, sort of like when the Justice Society of America showed up for two episodes of Smallville.
And what a cheap bastard he is. These spots have great production values, but only one President gets to speak in each of them, and Lincoln’s line is an obvious studio layback. I guess Barber hates unions so much he won’t even spring for an AFTRA fee.
