Okay, I keep a vast menagerie of peeves as pets. Heres one.
The name of the Roy Orbison song is not Sweet Dreams, Baby. Its Sweet Dream Baby. (Or, strictly speaking, just Dream Baby.) Hes not wishing her sweet dreams; its not a lullaby. Hes saying that shes his sweet dream baby, the subject of his sweet dreams. (Dreams whose fulfillment is not necessarily to be expected.) Listen, you can hear that hes singing sweet dream baby and not sweet dreams, baby, even if the person who uploaded the song to YouTube labeled it Sweet Dreams, Baby:
Among the factors that have contributed to the confusion is a commercial from a few years back; I forget what the commercial was for, but it showed a kid eating a cookie (though it wasnt an ad for cookies) while playing a version with dreams in the lyrics. Another is this iconic performance, where it can easily sound as though Orbison is singing dreams:
But if you listen carefully and watch both Orbisons lips and those of Bruce Springsteen, whos accompanying him here it becomes clear that Orbison is still singing dream and its Springsteen whos adding the S. Thats right: while backing up Orbison at an Orbison tribute, the Boss is singing the wrong goddamn lyrics.
