 Jack intros guest Nat King Cole as the best friend a song ever had, in Nat s final TV performance before his death. Nat banters with Jack, plus croons "When I Fall in Love" and "Day In, Day Out." Nat reluctantly consents to sit in on piano for Jack on "Sweet Sue." At their rehearsal Jack s sax player injures his drummer s arm in a fight, so always-cool Nat calls in a 5 year old (James Bradley Jr., later played with Anita Baker and Chuck Mangione) on the skins.
