Harry Muskee of Cuby And The Blizzards with Van Morrison
 
In March of 1967, after leaving Them, Morrison toured the Netherlands with Dutch group Cuby And The Blizzards as his backup band.

Here they are doing “Mystic Eyes” in a video clip that I wish were longer.

Update: Dangerous Minds reader Knickerbocker noted that the audio portion of the video is taken from the original 1965 release of “Mystic Eyes” by Them. Good ears, Knickerbocker.
