Motown's 50th anniversary was celebrated in style in 2009 - a year before The Second Disc even existed - with some excellent box sets and reissues. But this year marks another important set of golden anniversaries for the label: the debut of Motown's world famous groups, The Supremes and The Temptations. And no commemoration would be complete without a little bit of product to attract fans and collectors.

With that in mind, Hip-o Select announced over the weekend a pair of triple-disc sets commemorating the singles (both A- and B-sides) of each group for their 50th anniversaries. The Supremes' 50th Anniversary: The Singles Collection 1961-1969 focuses exclusively on the years Diana Ross led the legendary girl group. But that focus means you get the lesser-told parts of the narrative, too: the group's early flop singles leading up to that glorious run of five No. 1 singles in 1964 and 1965; a rare Phil Spector-produced radio single; the excellent foreign sides collected on Motown Around the World: The Classic Singles and more.

The same red-carpet treatment is afforded for The Temptations on their set, going through "My Girl," "Ain't Too Proud to Beg," "The Way You Do the Things You Do," "Psychedelic Shack" and "Just My Imagination (Running Away from Me)," in addition to the typical bonus fare - international singles, early rarities and - in a bit of overlap between The Supremes' set - all of the original A- and B-sides that brought both groups together. While the set only covers the band's first decade, thereby leaving out a major hit in "Papa Was a Rolling Stone," the song selection is a thorough overview for fans with money to spare.

Of course, collectors have one burning question about this set...and we're going to do our best to answer it after the jump.

For most collectors, having all the single sides from The Supremes and The Temptations is one thing. It's another thing to know how the songs will be presented. After all, for most fans who grew up with these songs, they were heard on mono 45s. (The Complete Motown Singles boxes, of course, included both stereo and mono mixes.) So which masters will be used?

The answer is...both. Universal's official track list indicates some songs will be in stereo and some in mono. Surely there's a method to the madness? In any case, both sets are available to order from Hip-o Select (as well as Amazon, where both sets are available immediately as MP3 sets), and you can view the track lists below.
