A carnival of characters- well known in their respective fields- that ranges from Percy Grainger, ""the running pianist"" of the title, to Gargantua, the gorilla, and others of equally eccentric personalities. There's Flaherty, outstanding in documentary moving pictures; Joshua Lionel Cowen, exuberant and peppery chairman of Lionel Electric trains; Slotkin, an artist in the meat business; Phil Watson, tempestuous ice hockey pro; Eugene F. Moran, frenzied head of the tugboat company bearing his name; Dr. Samuel J. Crumbine whose determined battle on public health questions has had international results; the Flying Concellos who have made serial and circus history; Bobby Clark, one of the last of the old school comedians; and Mrs. Rosalie Barrow Edge, ""common scold"" to the Audubon Society and rabid conservationist- all in their unique exploits and irrepressible individualism. This highly entertaining gallery of odd souls is punctuated by random fictional sketches of unequal effect- the profiles are the real diversions for your money.
