Was, um, "drivin' in mah cah" yesterday when "Satisfaction" came over the radio in a mix wildly different from what I'm accustomed to: piano, very prominent acoustic guitar, etc.
I gather that this is the "true stereo" mix. Are there others? Is the one on Out Of Our Heads, which seems to feature very prominent tambourine, different from the single?
But the short answer is three. American radio stations use the wide-stereo version that you heard. And for some reason, when it's on radio, the acoustic guitar seems even more prominent.
