Blackheart Man is a a great album. To be honest, after the original Wailers split up, he played 3rd fiddle to Marley and Tosh, but he had a much longer innings than both of them and is rightly regarded as reggae royalty.
He didn't like the weather in London - one of the reasons he didn't want to tour, which led to the parting of ways with Bob n Peter. Wonder what he would have made of Scottish weather....
