Having been asked to record Apache from scratch recently (for a friend who wanted to play the lead and bass parts), I listened to the Shadows original with 'a fresh pair of ears'.
The 'original' that I used was from 'The Shadows The Collection', a 3-CD box set issued by EMI in 1996. This has Tony and Cliff panned hard left, Jet's bass fairly indistinct, but seemingly also left, Bruce panned hard right and only Hank in the middle. I didn't have the mono single version to hand.
Am I correct that this stereo version was made at the same time as the mono version, but in a separate control room using split feeds?
Also, the conventional wisdom is that Cliff plays the chinese drum at the beginning and at the end, but is that he, or is it Tony, playing four to the bar during the 'staccato' section from 1' 30"?
