This week "Sunday Morning," hosted by Jane Pauley, features Susan Spencer's cover story on loneliness, and how recent studies point to the health effects of being alone. Plus: Tony Dokoupil sits down with Dolly Parton, the Grammys' MusiCares Person of the Year; Lesley Stahl interviews filmmaker Spike Lee, a first-time Best Director Oscar-nominee for "BlacKkKlansman"; Serena Altschul checks out the fluorescent beauty of rubies; Anthony Mason visits the fabled Electric Lady recording studios in New York's Greenwich Village; and David Pogue witnesses a 21st century anachronism: singing telegrams.
