It's March 21st, and on this day in 1961, Elvis began recording the soundtrack for *Blue Hawaii* at Radio Recorders in Hollywood. The session started at 1:00 p.m. and continued until late that night, wrapping up around 11:50 p.m. Over two days, Elvis and his band recorded 15 tracks, including the iconic "Can't Help Falling in Love," which would go on to become one of his most beloved ballads. The session also brought a distinct Hawaiian sound to life, with the use of steel guitars, ukuleles, and percussion by the legendary Hal Blaine. Interestingly, different versions of "Can't Help Falling in Love" would later be used in the movie and the final master recording. It wasn't until 1997 that the definitive version of the song was released on the *Elvis Presley Platinum* box set.
