[3] Lennon overdubbed his vocals onto the final take, and Harrison recorded lead guitar parts, including one with a heavy tremolo effect.

[4] According to musicologist Walter Everett's description of the recording, Harrison played all three of the electric guitar parts, including one that doubles the main riff on a Rickenbacker 12-string.

[5] Author Ian MacDonald cites the varied sound treatment applied to Lennon's vocals and Harrison's guitars as an example of the Beatles' increasingly experimental approach to production during the Help!

[4] In MacDonald's opinion, the song is a "twee make-weight" that, while "slightly redeemed by the vigorous chorus", features the "hollowest" lyrics of Lennon's career.

for AllMusic, Stephen Thomas Erlewine considers "It's Only Love" to be one of the rare "minor numbers" on an album where Lennon dominates the songwriting with "great" contributions such as "Ticket to Ride", the title track and "You're Going To Lose That Girl".
