In the song, the narrator (Smokey Robinson) describes how if he feels that if his first attempt at trying to show his lover affection was not good enough, then he'd try something new to keep their love alive:
I will build you a castle with a tower so high it reaches the Moon. I'll gather melodies from birdies that fly and compose you a tune. Give you lovin' warm as Mama's oven, and if that don't do, then I'll try something new.
The Miracles issued the original version of the song in 1962, and with wife and fellow Miracles member Claudette's voice clearly audible in the chorus (hey Venus...). Smokey and Motown founder Berry Gordy produced the song with an Oriental feel to it, with unusually lush-for-the-period orchestration and sweeping strings, showcasing The Miracles' harmonies and Robinson's production style.
In 1966, R&B artist Spyder Turner covered the song as an excerpt of his hit cover of the Ben E King song "Stand by Me". Several years later, in 1969, the group's Motown label-mates The Supremes and The Temptations released a duet version that became a hit reaching number 25 on the Hot 100 and number 8 on the R&B chart. Disco/pop group A Taste of Honey also covered the song 20 years later, in 1982.
