Thanks Phil.
Bruce, when the single version of Roundabout was played on the radio, in the mid-seventies, I recorded it on my little Sony cassette recorder. Remember the slogan, 'Home taping is killing music'? It didn't, because soon after I bought the album and eventually CDs. I know it sounds ridiculous, but the vinyl sounded almost too good and I wanted to recapture the sound of the radio broadcast from my original recording. They used to say how things often, inexplicably, sounded better on the radio. It's probably because we associate them with a time and events, which is certainly the case for me with Roundabout.
They always "weighted" the signal when they played our old music on the radio so it sounded different than what you heard when you played it at home. FM broadcasts are about the equivalent of a 128 Kbs MP3 file as far as quality goes, or maybe even a little lower. But I agree with you there are a handful of songs whenever I hear them no matter where I am or what I am doing that instantly transport me to a memory from my childhood. Get Back is one of them permanently etched in my mind sitting around the campsite in Red Deer when I was 9 or 10 years old.
I laugh when I think about the panic back in the day as well Martin, the only thing that happened when audio cassettes hit the market and the tape and players improved in quality was the labels made MORE money.
