Motorola Stereophonic High Fidelity - Progress In Sound - Magic Moments In Music, 10&amp;#8221; promotional disc. &nbsp;From the liner notes: &nbsp;On Side #1, narrator Norman Ross, in a fascinating saga of &amp;#8220;Progress in Sound&amp;#8221;, guides you through a review of the inventions of the ages to which man has lent his ear. &nbsp;You go from the savage&amp;#8217;s primitive tom-tom through early forms of the telegraph and telephone&amp;#8230;past the first phonograph and its limited, unnatural tones&amp;#8230;until you reach your destination: Sound&amp;#8217;s most amazing expression,&nbsp;Stereo High Fidelity,&nbsp;as it has been perfected by Motorola. &nbsp;You&amp;#8217;ll chuckle as Ross interviews such sound &amp;#8220;experts&amp;#8221; as Sir Trafalgar Whitley, Miss Maude Frickert, and B.B. (&amp;#8220;Big Biz&amp;#8221;) Bindlestiff - all the creations of the famous satirist and zany vocal-effect virtuoso, Jonathan Winters.
