This is a question that can be answered by a "Kinks" fan, and someone
who watches T.V commercials. In that I know of a commercial that has a
main theme song that,...  H.P.I just remembered it is a new commercial
for H.P. and "Their digital photography", great visuals in commercial,
But Is that "The Kinks" song playing in these H.P Commercials and if
so which one , or else who is it?

The song is "Picture Book," performed by the Kinks.
