Jigsaw - Who Do You Think You Are

Who do You Think You Are is a song written by Des Dyer of Jigsaw .
The band released their version as a single in a few European countries but not in their native UK where they allowed band Candlewick Green to record a version ( they shared the same management ) and it was a 1974 top 30 hit single for them.
In the USA the song was recorded and was a hit single for Bo Donaldson and The Heywoods .
The Candlewick Green arrangement is virtually identical to the original Jigsaw version although I think the hook line of the Jigsaw version is more powerful.
It has in recent years been recorded by Saint Etienne
