"Can't Take My Eyes Off You" is a 1967 single by Frankie Valli. The song was among Valli's biggest hits, earning a gold record and reaching #2 on the Billboard Hot 100 for a week, stuck behind "Windy" by The Association. It was Valli's biggest solo hit until he hit #1 in 1974 with "My Eyes Adored You". "Can't Take My Eyes Off You" has had a major cultural impact, with hundreds of cover versions, many of which have been on the charts themselves in different countries. The song is a staple of television and film soundtracks, even being featured as part of the plot of some films, such as when the lead characters sing or arrange their own version of the song. The Valli version was also used by NASA as a wake-up song for a mission of the Space Shuttle, on the anniversary of astronaut Christopher Ferguson.
