Hi and Ho-Double-Ho to all — this Christmas night, it is the Mostly Singles Leftovers Show: cool sides that did not previously make it to air this year, but every one a gem. Featuring two (!) U.S. premieres from New Zealand. Cozy up, close your eyes, boogie in your dreams. Mostly Singles presents selections from an extensive collection of 45 rpm vinyl — music from the 1950s, 60s, 70s, and early 80s, mixed with 78 rpm selections from American popular song and field recordings from the Library of Congress and folklore archives.
