Was hearing Rolling Stones '30 Greatest Hits' This is a 1977 German pressing by 'Arcade Records'. While it includes the classic hits like "Ruby Tuesday" and others, the recording quality was not liked by me. Also on play was Louis Armstrong 'Greatest Hits'. This is a Gramophone Company of India pressing. While the sound is in simulated stereo, I discovered , much to my chagrin, that abroad it is sold as a 2 LP set, while here this was a single LP with half the songs !
On another note , Satyaki's 45 rpm EP collection looks truly superb. In the seventies, an SP and EP cost less than ₹8/- & ₹14/- respectively. A fair amount in those days!
