“Can’t Take My Eyes Off You” is a 1967 single by Frankie Valli. The title is a shortened version of composers’ title of ‘Can’t Take My Eyes Off Of You’ which has led to long-term confusion over the song’s title – although the Valli record is correctly titled and based on the original song title. The song was among Valli’s biggest hits, reaching #2 on the Billboard Hot 100 and earning a gold record. It was Valli’s biggest “solo” hit until he hit #1 in 1975 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.
