That's fascinating. I can remember pre-internet days being resigned to not knowing stuff. For example albums in my country generally didn't include the lyrics. Every time it came on the radio, I asked people what was the singer saying over and over in REM's "The sidewinder sleeps tonight". Nobody knew. Another was a foreign language pop song I remembered from when I was on holiday abroad as a teenager. I searched fruitlessly for it in record shops at home. Decades later, on a whim I found it by googling and then the original video on youtube (I'd only heard it on juke boxes)
