"The Cabaret Beat" WAS a good read, I agree. But I wondered as it meandered into a history of the author, Ian Frazier, his father, the New Yorker editor and founder Harold Ross, the MacKay family founder (John), Mark Twain, MacKay's wife Louise, their youngest son Clarence, his wife Katherine Duer, and a great granddaughter Katherine Barrett Swett before coming back to the subject of the story, Ellin MacKay Berlin, and her husband Irving Berlin. I settled down to read the rest of their story, but wait! The article then veered off into Irving (ne Israel) Berlin's family history starting in Siberia. Then back to John and Clarence MacKay with cameos from Leopold Stokowski and the Prince of Wales, back to Ross and TNY, and finally winding up with Ellin and her 2 articles, finishing with an interview with her aged daughter. Whew!!
