^ That would be a nice one to get, since I do like that song. Didn't realize it was a cover.
Generasia tells me that Anzai Maria released her single of it in 1973, and the original English language version by Emy Jackson and the Smashmen was released as a single in 1965, so yeah, both of those are on 7-inch vinyl. YAJ currently has reasonably priced copies of both versions, so I might just check the listings next time I do a round of From Japan/Yahoo Auctions.
(I actually have a track by Emy Jackson on a wonderful compilation CD called Nippon Girls, but it's not "Namida no Taiyou".)
EDIT: And of course there are YouTubes of both versions. The surf guitar on the Emy Jackson version is just too cool.
