"Y'arriva" is on an acetate demo, probably thought for Cliff Richard. It features Bruce (lead vocals) and Hank (harmony vocals) accompanied by rhythm guitar only, no organ or other keyboards at all.
Also on an acetate demo, "Big Top Blues" has lead and rhythm guitar, drums and piano. I don't hear a bass guitar (my copy is not of best quality). In most cases Hank plays the piano, but it might also be someone else (Norrie?).
I don't know "Mango". However, if "Mandingo" is meant, this is also an acetate demo played by piano, rhythm guitar, bass guitar and drums. For the piano my guess would be Hank.
I hope this is of help.
