Great song. Was part of a "concept album" done by some of the biggest names in Rock history. Two different versions of the album were done Butterfly Ball and the Wizards Convention and Butterfly Ball and the Grasshoppers Feast. Slightly different track lists.
Imagine television in the USSR, 2 central channels and 1 regional. Although this horror had one plus: it had no commercials or breaking news, so during breaks in sports matches we were shown cartoons, on the regional channel in Georgia we were shown rather rare videos for such a totalitarian country. And I, a small child, sat and watched a football match to see Love Is All and Animals Football (a piece from the film Bedknobs and Broomsticks) during the break. When I grew up, I began to look for the original sources and discovered that Love Is All is my favorite Dio and Deep Purple.
If you really wanted to know who was singing, why didn't you just look up his name? There's a computer right in front of you. I think it would look good in the video, but you guys always end up in a hurry
