Blame When Harry Met Sally. This song’s appearance at the 1989 romantic comedy’s climax (“I’ve been doing a lot of thinking, and the thing is, I love you.”) forever solidified it in the hearts of lovers everywhere. Long an reliable in the Great American Songbook, “It Had to Be You” has been covered by everyone from Billie Holiday to Frank Sinatra. For the When Harry Met Sally soundtrack, director Rob Reiner tapped Harry Connick Jr. to sing almost a dozen standards, including a version of “It Had to Be You” that has been played at thousands of weddings since. Couples likely take comfort in the line, “With all your faults, I love you still.” That sentiment has probably kept more marriages together than any set of official vows could.
