By the time The Monkees' fifth million-seller album The Birds, The Bees & The Monkees was issued by Colgems in April 1968, stereo had become the preferred listening experience and albums issued in mono were quickly being phased out of production. As a result, the mono mix of the Birds album was extremely limited in quantity and today is a highly, highly sought-after collectible due to its exclusive mixes and all around unique listening experience. The mono mix of The Monkees' eclectic 1968 LP was finally issued on compact disc in 2010 as part of Rhino's 3-CD deluxe edition.
