BTOs Not Fragile is a very satisfying album to listen to and probably BTOs best album. The song called You Ain't Seen Nothing Yet only made it onto the album when BTOs manager said the songs on this album were all good but they needed a 'killer track' on the album to guarantee a 'hit album' so a song that was regarded by the band as a 'joke song' and used in rehearsals to 'warm up the band' and known as 'the work song' was given the name You Ain't Seen Nothing Yet and was included on the album and the rest is history...
