I don't often see the term narcissism misapplied that way. Regardless in this case I admire Art Garfunkel, the singer. But he clearly has delusions of grandeur. Not my opinion alone, to wit this Washington Post review of one of his memoirs:

"The subtitle of Art Garfunkel's new memoir, " Notes From an Underground Man," echoes Dostoyevsky's "Notes From Underground" and Richard Wright's story "The Man Who Lived Underground" — both serious works of literature.

Garfunkel’s book, however, is a splattering of 30-plus years of handwritten thoughts, lists, travel notes, bad poetry, confessions, snarky digs, platitudes and prayers gussied up for publication in different fonts and sizes.

Reading it is like rummaging through a huge junk drawer of the mind."
