According to Greg Adams, writing for All Music Guide, the song "exemplified the groovy state of instrumental music at that time." In Bob Crewe's version, a trumpet plays the whole verse, the first time around, sounding like Herb Alpert's Tijuana brass style. The second time the verse is played, a half step up in tone from G minor to A-flat minor, a tenor saxophone plays a jazzier version, accompanied by strings and a harpsichord, that play a counter-melody. The trumpets finish up the refrain, and all of the parts are played, repeating the first part in the coda, before the fade.
Other instrumental versions of the song were recorded by Billy Vaughn, Chet Atkins and Walter Wanderley. A vocal recording by Andy Williams, featuring lyrics written by Tony Velona, went to #34 in the United States, and after it was used in a Fiat ad in the UK, the re-released single reached the top ten. The version by Al Hirt reached #31 on the Adult Contemporary chart and #119 on the Billboard Hot 100 in 1967.The Higsons covered the vocal version in 1984; this was released on a single and the album The Curse of the Higsons. A French-language version, "Le jeu du téléphone", was recorded by Lucky Blondo, which was covered by Natacha Snitkine and also Ginette Lemieux (under the mononym Caroline).
