All three two-part appearances on Later with Bob Costas have been separately uploaded by others in various levels of completeness and clarity. These here come from my own tape collection. All are complete, though, due to copyright caution, I’ve edited out all of the music and film clips that were inserted into the interviews for air.

Also included are the promos for the shows that aired during The Tonight Show station breaks (though I couldn't include the promo for Nash, Part 2).

And a coda. For David.
