Some pre - Les Rallizes Denudes action:
The Jacks

Too original to fit under the Group Sounds moniker. This song is the b-side of their 1st 45, but was left off their lp, Vacant World. Great sound influenced by the San Francisco Bay area sounds, especially the Jefferson Airplane. Unlike other japanese groups of the era, the Jacks didn't slavishly copy sounds or even cover famous songs of the day.
