For those who asked, this tape was recorded in a private house in the Cambridgeshire (UK) sometime during the mid 50s / 60s. I don't have any evidence that would suggest there may have been a TV in the recording space (might be a possibility though).
Richard, thanks for the ideas. I'll look into your suggestions when I'm back in the studio tomorrow and report any findings.
Cheers
