I will check with my dad once he gets up - it's a hard life in isolation - but I think it was white. Maybe it was I Can Help and I'm assuming it was mid 70s as that's when the song dated from.
It would be a bit strange for my granddad to have it as he wasn't a collector or records, he just enjoyed the music, but he did have a very early Marty Wilde promo and a couple of Sun Jerry Lee singles and the gate fold Elvis Christmas EP.
Oh I miss that man.
