Great find, thanks for the upgrade! This is one of my favourite Tanner/Media General LPs.
The Wurlitzer sound on these is great. "Free Fall" seems more than a little inspired by "Riders on the Storm".
It's not a term in wide use, but I would assume "Donut", a circular thing (a particularly American circular thing, at that!), means rougly "with edit points, loopable" or "combination of below intro/outro elements".
Did you find this in Singapore? I wasn't aware Tanner had much international distribution.
