Grinderswitch Biography (Wikipedia)
Grinderswitch was an American southern rock band. They recorded a number of albums for Capricorn Records in the 1970s, but never achieved the same widespread recognition enjoyed by some of the label's other artists, such as The Allman Brothers Band and Marshall Tucker Band. They also recorded for Atlantic. In the UK they are perhaps best known for their recording "Pickin' the Blues", which was used for many years by the disc jockey John Peel as the theme tune for his BBC radio shows.
