it's the Belgian "summer of love" anthem... a great flower-power song that was a big hit all over Europe in 1968. For those who don't know it, do a search on the web for a soundclip...

Yes!!!! Found it!
I live in England (nearly 20 years, but am originally from Holland. Saw twice a new commercial the last 2 days on tv here (can't remember what it was for), but regonised the song that was played in it (although it wasn't the original version). I knew it was a hit in the sixties. And always liked it. But hadn't heard it for years! My partner ,who's english, knows and does remember a hell of a lot about (popular)music and whenever a song is played HAS to announce WHO, WHAT and IN WHICH YEAR IT WAS A HIT! Get's a bit annoying at times.
He said he knew it from a "chill"-album, but I told him I was certain that it had been a hit in the sixties.
After surfing the web for an hour orso tonight, and not even quite sure if the title was "Daydream" and not knowing at all what the bands name was. At some point I found out that it could be Wallace Collection, but eventually after finding your website, and you were the only one I was able to hear that song, I got it right!
Thank you so much. The song brought back so many memories! I will keep your website in my favorites list. It was a great help.
Thanks again, Trijnie
