Spiral Staircase - Proud Mary

It was at the end of 1970 when I first heard this song, Proud Mary by Spiral Staircase, at a farewell party in a house off Jalan Imbi, K.L. It was a really hot song then, to start a house party going. At the time, I presumed it was their original song. It was some years later that I discovered Proud Mary was a Credence Clearwater Revival's classic. But it took a hard-hitting touch to it to make it to No.1 in the local chart (if not mistaken) and brought to the attention of the general public.
