'Now and Then'

The final song from the iconic English rock band The Beatles was released yesterday, a track that relies on AI-enhanced vocals from former co-frontman John Lennon. Listen to the song, titled "Now and Then," here.

Regarded as one of the most influential bands of all time, The Beatles are the bestselling artists in music history, having shipped more than 180 million albums. Lennon, Paul McCartney, George Harrison, and (for most of the time) Ringo Starr, were nominated for 21 Grammys in the span of six years beginning in 1965.

The group broke up in 1970, and Lennon was tragically killed by an angry fan in 1980. The new song was originally written by Lennon in 1977 and surfaced in 1994 by McCartney but was shelved due to Lennon's voice being muffled by a piano. New technology reportedly allowed Lennon's vocals to be isolated and enhanced to the point of being usable.

A short film about the song's production was released late Wednesday—watch it here.
