The Best of the Goon Shows (around 1960).
Due to my tender years I only got to hear their last 2 or 3 shows on the radio, but I was an instant Goons fan. I bought the Best of the Goon Shows #2 soon after and if I remember rightly, my next album wasn't until the Beatles released "A Hard Day's Night" (in 1964?).
Back then, albums were too expensive for kids to buy regularly. Come to that, most of my early singles were (Woolworth's) Embassy cover versions:
