"Heart of the Night" is a song on the 1978 album release by the country-rock group Poco entitled Legend; the 1979 hit single is also featured on the group retrospective 20th Century Masters, as well as The Essential Poco.
"Heart of the Night" is highlighted by an alto sax solo by Phil Kenzie who had similarly and memorably contributed to the Al Stewart 1976-77 hit "Year of the Cat": Kenzie had become acquainted with Cotton and Young as a result of Kenzie's playing behind Al Stewart during the 1977 Year of the Cat tour which featured Poco as opening act. Two other members of Al Stewart's tour band, drummer Steve Chapman and bassist Charlie Harrison, also played on the sessions for the Legend album. Paul Cotton: "Steve Chapman, right after we rehearsed "Heart of the Night" in the studio, said "Man, that’s going to be a big hit."
