[Taunton Blue Genie]

Although Dundee United have had the colour orange in their kit for ages, Blackpool's shirt colour is often considered unique in the Football/Premier League and yet there was a time in the 70s when three other Football League sides played in orange, or variants of that colour, shirts, - one of them even used their shirt colour in the name they gave their programme at the time, can you name the three?
