The sticky shed faeries were with you? Like one tape that exploded on me
but only the guitar intro was lost...the deceased singer's vocal was intact.
Anyway...seriously, perhaps being under high-pressure at the hub helped,

As you know, plastic bags (I think generally polyethylene) are not
excellent vapor barriers, so your guess is as good as mine.
Thanks for sharing.
