Very good job, that is a song not easily covered with the rhythm and harmony vocals and your vocalist even looked a bit like young Coverdale!
In effect, this song is a Cream pastiche around a Blackmore riff that somehow snuck on the Burn album. Coverdale and Hughes were open about the fact at the time that they had tried to emulate Bruce's/Clapton's harmony singing on this particular track. They did it quite well too, I think.
