From a reader who was at our D.C. fundraiser in September:

I don’t recall the song Derb was singing in those pics, but looking at them, it seems that it might be “Mr. Roboto.”
(top to bottom)
Pic 1 – “You’re wondering who I am — machine or mannequin (manny-can)”
Pic 2 – “With parts made in Japan…”
Pic 3 – “I am the modern man!”
Pic 4 – “Domo arigato Mr. Roboto, domo…domo”
Pic 5 – “The time has come at last, to throw away this mask, so everyone can see, my true identity…”
Pic 6 – “I’m Kilroy! Kilroy. Kilroy. Kilroy.”
