"Thank You Girl" is a song recorded by the English rock band the Beatles, written by John Lennon and Paul McCartney.

Originally titled "Thank You, Little Girl",[3] the song was written by John Lennon and Paul McCartney as a tribute to the band's many female fans.

Lyrically, Ian MacDonald suggests that Lennon probably wrote the first line of each verse, allowing McCartney to use his flair for word play and inner-rhyming in completing it.

According to multiple sources, John came to the session directly from bed due to a severe cold.

Engineer Geoff Emerick said it took John numerous takes to produce a satisfactory result because he was so unsteady.
