First recorded by Roger Daltry (1973).
Hit version by co-writer Leo Sawyer (US #96/UK #6 1974).
From the wiki: “‘One Man Band’ is a song first recorded by The Who’s lead singer, Roger Daltrey, for his debut solo album Daltrey. It was written by David Courtney and Leo Sayer (‘The Show Must Go On‘, ‘More Than I Can Say‘), and features Daltrey’s Acoustic guitar strumming. According to Daltrey, it ‘reminiscences of Shepherd’s Bush’ (a place in west London where Daltrey had grown up and where The Who were formed) and became one the albums highlights; later being released as a single in its own right in some European territories but without any US chart success.
“The song was covered by the co-writer, Leo Sayer, a year later for his solo album Just a Boy and was also released as a single which later became one of Sayer’s biggest UK hits.”
