The Three Reeds were a nightclub harmonica trio; Maurice Vint played a chord harmonica, Harry Cooper a bass and Bob Higgins a chromatic. This site states that the Reeds were Canada's top harmonica group for over ten years, during which time they toured the country and added chromatic player Bernie Bray as a fourth member before breaking up in 1974. Other than that I don't know much about the group, although the liner notes (which I've edited for length) include an amusing story and a bit of technical information about their live act:

"A story has been told of the harmonica player who lost his music just before a concert. The leader of the orchestra offered him a copy of the piano part only to have his offer turned down. The harmonica player eventually found his music, which was a scrap of paper bearing the words "BLOW, SUCK, BLOW, BLOW," etc...The Three Reeds, one of the fastest rising night club acts in North America, have a unique sound. Most harmonica groups use ordinary amplification with microphones on stands. The Reeds found this method too confining...They eventually came up with the idea of using larynx mikes attached to their throats and by using long leads to their amplifiers. This method gave them freedom to move anywhere on the stage."

The Golden Harmonica Hits Of The Three Reeds was produced by Ken Warriner (who also produced Phil La Penna's record and played vibes on Sharon Strong's album) and engineered by Bill Roncken. So is it pop music? Country? Jazz? The answer is all of the above and none of them, exactly, as these songs take on a unique flavour when performed entirely - rhythm, melody, the whole works - on harmonica (the only hint of any other instrumentation is a tiny bit of percussion on "Night Train," a cover of the jazz/r&b standard). "Cuando Cuando" is a Latin-tinged number that seems to be most associated with Engelbert Humperdinck. "What Now My Love" is another song that has been recorded by everyone, and it chugs along jauntily enough for a tune about someone who has decided to commit suicide after being left by their lover. And "Yesterday"...well, you know that one.

More Three Reeds? Why not! This album, another Arc release, was also produced by Ken Warriner, with extensive liner notes by John A. Smith. From those liner notes, an interesting description of a Three Reeds gig:

In lounges and supper clubs across the country, the Reeds demonstrate their proficiency and vastness of repertoire time and again in a little game they play with their audiences called "stump the band." The game is very simple - the boys call for requests, and the deal they make with the audience is such that if they can play the requests, then the people making the requests must buy the group drinks. If the group can not play the requests, then it their obligation to buy the requestors drinks. To date, the boys have not had to buy anyone a drink under this arrangement.

I would have loved to see three harmonica players getting drunk on stage playing a list of requests from the audience. That would have been wild. From "The electro-harmonic sound of The Three Reeds" here are a few more great tracks:
