Year of Release: 1967
Warm Sounds were essentially the duo Denver Gerrard and Barry Younghusband who worked primarily as Andrew Oldham's right hand muso men for the Immediate label. If a band required a stray song they might have (such as "Black Sheep RIP", for example, which was theirs) or needed some competent vocal harmonies or smart instrumentation, Denver and Barry were beckoned.
Their own particular waxings under the name of Warm Sounds were, perhaps unsurprisingly, generally gentle and wistful affairs, like West Coast pop with soft English vowels thrown into the mix. "Birds and Bees" is all lazy vocalised noises which would be described as scat if they were energetic enough ("Ooh bap bap, ah bap bap" is the closest I can get to transcribing them) pinging glockenspiels and idle basslines. Some people would probably refer to this as "popsike".
Whilst "Birds and Bees" did well enough aboard the good ship Radio London to climb to to pole position in that station's chart, it only got to number 27 in the official charts used by the music industry, supposedly the lowest position a Radio London number one has ever occupied in the real world. We shouldn't pay too much heed to this fact, since their chart was largely based on airplay, guesswork and whoever the station owed a favour to at any given point, but its safe to say that there were probably many disappointed faces at the Deram offices as a result.
It was also the duo's only hit. Follow up singles "Sticks and Stones" (on Immediate this time) and the rather berserk "Nite is A Comin'" (back on Deram again) were ignored by the public despite picking up further radio play, and the concept of Warm Sounds was subsequently put into the chest freezer. Younghusband later worked with Donovan in his Open Road band, whereas Denver Gerrard released a solo album "Sinister Morning" which wasn't greeted with much more enthusiasm than the later Warm Sounds releases.
