Bob Ferguson has 4 Jethro Tull concerts.

Jethro Tull is a progressive rock / folk rock band which formed in Blackpool, Lancashire, England in 1967. Their music is marked by the initially soulful and bluesy, and later expressively idiosyncratic, vocal style and unique lead flute work of frontman Ian Anderson, and their notable guitarist Martin Barre. Their songs feature unusual and often complex construction, incorporating elements of classical and celtic folk music, as well as art rock and alternative rock.
