The guy in the Goofy jumpsuit is Jackie Kahane, who attended Baron Byng along with a lot of other famous, and less famous, Jewish Montrealers. He was a standup comic and opened for Elvis Presley for something like seven years. Indeed, he did co-write, with Barry W. Adelman, and read the Eulogy at Elvis’s funeral, after Col. Tom Parker asked him to. A footnote: he was a writer on Bizarre!, the TV show that made John Byner and Super Dave Osborne.
