Many thanks lloyd1e. I have googled this until my fingers ache. I can find Ultra Nate but I can't find "It's All Over". Could it be "It's Over Now" which was at number 62 in the charts in 1989? They are not in the Guinness Book of British Hit Singles either.
The answer to your first question is Salvador de Madariaga born spain 1886, died switzerland 1978
Second one too the best of my knowledge is Ultra Nate, hope this helps
