Our car was bought in 2017. DH died early 2021. In all that time, I didn't realise that your car sound system can play the music on your phone. (Yes, I knew about the hands free, but that was all.)
Was driving one time and somehow the car system linked to the phone and randomly played John Denver singing "Lady, did you think I'd left you?"
I didn't even know that that was on the album. (I'm not great with tech these days.)
The next time it tapped into the system, it was the album of DH singing that came up.
He used to sing folk songs and as a youngish teacher would get some of the staff at school asking him to record cassette tapes to send to relatives in Canada and the like.
One of his pupils mum was a cleaner at the school and he'd recorded a cassette for her. Years later, the daughter was a mature student at the School of Scottish Studies at Edinburgh Uni.
She and her daughter (also a student at the uni) arranged to meet us at a local cafe and presented us with a memory stick to which the daughter had transferred the cassette. The pupil asked DH's permission to reference DH's singing in her dissertation and to deposit a copy of the music in hte SSS library.
Anyway, I'd copied it onto my phone - with a great deal of trial and error - and then the next time that the phone/car system went random on me, it was DH's singing that came up.
