While in Elf, Ronnie James Dio and Mickey Lee Soule participated Roger Glover's solo project based on a children's book "The Butterfly Ball". Ronnie James Dio sung three tracks on the album, as well as co-wrote two other tracks for it. The Butterfly Ball project consisted of many different musicians gathered together by Roger Glover. The project ended finally in March 1976, when a full-lenght video of The Butterfly Ball concert from October 16th, 1975 was released. Ronnie James Dio didn't participate it, though - he appeared only on the album and on a number of singles.
