"(I'm So) Happy Happy (You're Mine)" is the only single from the British girl group, The Sheilas, released on 17 (download) and 24 September (CD), 2007.
The Sheila's were a novelty group, created from session singers to promote Sheilas' Wheels, which advertised on ITV Weather in the United Kingdom.[1] The song lyrics include many references to this, for example, "You're my blue sky and sunshine", "Everybody wants the sun, nobody wants the rain" and "You can bring about a change in the weather".
