Suddenly needing material to fill out the album, the band dug back into earlier material such as ‘Wintertime Love’ and ‘Summer’s Almost Gone,’ yet 'Hello, I Love You' was still forgotten. Then 10-year-old Adam Holzman, Elektra Records founder Jac Holzman’s son, remembered it from the demo and told his father it would be a hit song. The single of ‘Hello, I Love You’ with a B side of ‘Love Street’ was released in 1968 and started climbing Billboard’s Hot 100 charts and soon hit #1 in the country.At the time this 1968 single was released, stereo 45 rpm records were generally unknown — especially in the Top 40 format. This recording by the Doors was promoted as the first rock 45 rpm record in stereo. It includes a long musical sweep about 1:20 into the song, starting at the left channel and panning across into the right channel.
The musical structure of the song is very similar to The Kinks' song 'All Day And All Of The Night.'But in the liner notes to 'The Doors Box Set,' Robby Krieger has denied the allegations that the song was stolen from Ray Davies. Instead, Krieger said the song's vibe was taken from Cream's song 'Sunshine of Your Love.' But Davies has continued to assert that the Doors' song was based on his.In a 2012 interview with Mojo magazine, Ray Davies said:
‘The funniest thing was when my publisher came to me on tour and said The Doors had used the riff for 'All Day And All Of The Night' for 'Hello, I Love You.' I said rather than sue them, can't we just get them to own up? My publisher said, 'They have, that's why we should sue them!' (laughs) Jim Morrison admitted it, which to me was the most important thing. The most important thing, actually, is to take the idea somewhere else.’
In a 2014 interview with Rolling Stone, Davies suggested that an out-of-court settlement had been reached with the Doors.
The song has been covered by Oleander, Buddy Rich, Missing Persons, The Cure, Eurythmics, Simple Minds, Anal Cunt, Neil Young, Adam Ant, Adam Freeland, Siouxsie Sioux, Kiyoharu, the Lithuanian postmodernist rock band Antis, and the Persian alternative singer Mohsen Namjoo. Also, a hip hop artist Necro mixed and released this tune as 'You Ho.'The only other charting version of the song came in 2010 when a version by the cast of the TV series Glee went to #66.
