At first I thought that was CSI New York, it was only later that Crosby, Stills, Nash and Young sprang to my mind.
Us kids and our TV shows-induced thinking...
P.S. I love that article:
Whether and when Crumb ever recovered the originals from Zahn is unclear, and sources differ on the matter.
And given that in this case “sources” mostly means guys around 70 who used to take a lot of drugs, that they’d all remember things differently should hardly come as a surprise.
