"The Shoop Shoop Song (It's In His Kiss)" is one of the most beloved 1960s girl-group-styled hits, even though the woman who sang it, Betty Everett, might be more comfortably classified as a soul singer than a girl-group-like vocalist. There are a couple of unusual things to note about this tune's construction, though the melody was so catchy that not many people would think to catch them. First is that it starts with a two-line section whose melody isn't repeated anywhere else in the song, a most unusual device, though an effective one, with Everett demanding to know if the object of her affections loves her. The second is that although it's titled "The Shoop Shoop Song," at no point are the words "The Shoop Shoop Song" sung. It gets its name from the infectious "shoop shoop" syllables sung by the background vocalists in the chorus, though it's helpfully subtitled "It's In His Kiss," words that are sung during the chorus and ones that would have made a logical (if less colorful) official title. Getting past these irregularities, what puts "The Shoop Shoop Song" over is the delightful, playful call-and-response between the backup singers, asking various questions about the lead singer's boyfriend. Everett responds in bolder, more declarative tones, culminating in the catchy chorus that's backed by the "shoop shoop" noises, finished off by the backup singers chanting "that's where it is," rejoined by Everett's "oh yeah!" These verses capture the spirit of "girl talk" about romance with great verve and humor. There's also a cool bridge in which the backup singers harmonize in ascending patterns. The quirkiest features of "The Shoop Shoop Song," though, are the clattering xylophones, which take the lead in the instrumental break with what sound like deliberate off-key notes, as if to mimic the foolish way lovers swoon as they're succumbing to passion. The brief burst of cha-cha horns at the end of the break is just another neat tic on a most creative and enjoyable record, which made the Top Ten in 1964.
