In The Land Of Grey And Pink*is a tune from Caravan, a progressive band that falls into the Canterbury sub-genre. This style features some jazzy elements, frequently with unusual chords/progressions and somewhat whimsical lyrics. It is mostly a strumming song but includes an intro that uses some 3-string chord shapes moving up the neck, along with a percussive strumming pattern.
