Let's Hang On on the Lowrey Aria

"Let's Hang On!" is a song composed by Bob Crewe, Sandy Linzer, and Denny Randell that was popularized by the Four Seasons in 1965. The recording reached No. 3 in the Billboard Hot 100 singles chart.
The popularity of "Let's Hang On!" has been attributed to the inclusion of several devices into the recording: a two-line introduction (sung by lead singer Frankie Valli), the use of two fuzz guitars (one guitarist playing low notes, another playing high notes on a fuzz bass), a chorus loaded with hooks and sung in falsetto, and backing vocals giving counterpoint with Valli's lead vocal. It re-established the group's presence in the Top Ten (of the Hot 100) as The Four Seasons were in a flurry of activity, recording albums both as The Four Seasons and as supporting musicians for Valli's rekindled "solo" career. In the UK, the song was a No. 4 hit for the group.
Billboard described the song as having a "hard-driving dance rhythm." Cash Box described it as a "hard-rockin' fast-moving rhythmic ode about a lucky fella who is mighty pleased that he's fortunate enough to have met the girl of his dreams."
