From the Barbara Cook New York Times Review

April 15, 2009

Of the many cabaret performances of hers I have attended, Tuesday's opening
night was the first at which I have seen Ms. Cook's blue eyes brim with tears.
"Goodbye, John," the song that elicited them, is an obscure, folk-flavored
ballad from the late 1940s by Alec Wilder (music) and Edward Eager (lyrics).
This stark, slightly elevated farewell, which holds out no hopes for
reconciliation, was recorded by Mabel Mercer (a champion of Wilder's music),
whom Ms. Cook cited as an even stronger early influence than her other idol Judy
Garland.
