Poor old Al Wilson - he always had his eye on something beyond the pigeon hole that was 'Soul' and his musical output reflects that - a bit like OC Smith, Freddie Scott, Nolan Porter and few others (to these ears of course). Take the album from which 'The Snake was taken - 'Searching For The Dolphins' - never a Soul song by the great Fred Neil and made famous by Tim Buckley (Poor Side Of Town was the flip of the Al Wilson version too). So how people can say 'the Snake' - in the context of that album or his output - is a terrible song I don't know, its a very, very clever song indeed! Because it was adopted by the UK Northern scene and played to death ever since was not his fault and he probably never even had the consolation of making any money out of it to boot!!
