Cover versions: Jackie DeShannon meets Kim Carnes

BBC Music has launched a poll to find the greatest cover version of all time. But many people do not know that some of the most famous songs in pop history were covers.

Kim Carnes' version of Bette Davis Eyes was the best-selling single of 1981 in US, spending 9 nine weeks at number one. But it was originally a 1975 album track by Jackie DeShannon.
