Wednesday Blues Surprises: look at this concert version of "Dreamer's Ball"!
It comes from the album "Jazz", 1978.
"Dreamer's Ball" is Brian May's tribute to Elvis Presley, who died one year before the album was released. You can notice that the arrangement for the live performance is completely different, with May and Taylor doing vocal brasses.
