Jethro Tull - Heavy Horses - 1. And The Mouse Police Never Sleeps

Heavy Horses is the eleventh studio album by Jethro Tull, released on 10 April 1978. It is considered the second album in a trilogy of folk-rock albums by Jethro Tull, although folk music's influence is evident on a great number of Jethro Tull releases. The album abandons much of the folk lyrical content typical of the previous studio album, Songs from the Wood (1977), in exchange for a more realist perspective on the changing world - as a clear mention to the title track, the album is dedicated to the “indigenous working ponies and horses of Great Britain“.
