I remember playing over and over and over "House of the Rising Sun" after mastering it on a new 12 stringed guitar, many moons ago.
And Sky Pilot is a GREAT song.
But I am so glad Justin was not hired for the Animals.
Who knows whose creative/musical 'voice' would have been more influential to the beginning sounds of The Animals?
JH may have lost his 'voice' in giving way to Eric's; which would have more than likely been the case - given Eric was doing the hiring and was founder.
 Justin may have taken a completely different tack and these magical treasures he's put out over these past few decades would not have been.
So glad it didn't work out.
