Cover art for Mountain People lyrics by Super Furry Animals

It's most definitely a song about the attitude towards the majority of Wales by the English authorities and those in English suburbia - out of touch with the reality of Welsh semi rural/valley life and seemingly apathetic to it, it's particularly about social neglect (investment and representation). You must remember that Wales was pretty much devastated in order to benefit the South East in the 1980's.
