The Jethro Tull song "Aqualung" idea came about from a photograph that Ian Anderson's wife at the time, Jennie (Franks) Anderson, took of a tramp in London. She wrote many of the lyrics for the song. Ian Anderson, has said, "She, in fact, was responsible for the lyrics in the first couple of verses. I suppose in total probably about half of the lyrics were words or word associations that she had come up with based on pictures of homeless men Franks had taken as a photography student." She is credited was co-writer of the song.
The Aqualung character is also mentioned in "Cross-Eyed Mary", the next song on the Aqualung album in this verse.
Laughing in the playground, gets no kicks from little boys:
Would rather make it with a letching grey
Or maybe her attention is drawn by Aqualung
Who watches through the railings as they play
