The Animals was a damn fine pop/rock/blues band.
Their cover of “House of the Rising Sun” was a masterpiece in performance by Eric Burden...and even today that voice & organ is hypnotic - absolutely amazing!!!
I was always partial to Zap Brannigan’s cover of this song “Leelah”
The organist was Alan Price. He was also Dylan’s organist when he toured the UK. Alan Price was only on the first two albums and some of the third. He had a fear of flying and when the Animals became popular and had to tour the States, Price bowed out. That original band with Price on keyboard and of course Eric Burdon’s vocals was as you said ‘amazing.’
