Just a Boy is the second album by Englishsinger-songwriter, Leo Sayer, and was released in 1974. It features cover versions of two songs written by Sayer for The Who's lead vocalist Roger Daltrey's debut album, Daltrey. The singles, "One Man Band" and "Long Tall Glasses" both hit the charts in the U.K. and around the world. Leo Sayer was now popular in Europe and made many promotional appearances there. He headlined in Paris at The Theatre D’ Champs Elysees, the theatre known as the home of his then-hero, mime artist Marcel Marceau.
The cover is a painting by Humphrey Butler-Bowden. It is a tribute to Antoine de Saint-Exupéry's artwork for his famous novella The Little Prince. The album's back cover pointedly depicted a group of new Sayers giving Pierrot the elbow.
Adam Faith, David Courtney and Sayer had already started work on the album, cutting "One Man Band" while Sayer was on an American tour. More recording took place in London. This time the recording went smoothly and the right results were quickly accomplished. Some of the songs, like "Long Tall Glasses", were written in the studio.
