Michael, I just looked out The Silver Tip, having established that you couldn’t be meaning The Silver Spear as the tune most usually called that doesn’t have the relevant figure in. The version of Silver Tip I found has got a cE dE cE pedal point passage in it, but the Cs are C#s (do you play naturals? - would work), which actually involves more fingerjumping than the C nats would, though I don’t find that a problem either - still vent my Ds!
BTW, I think your playing of Coachman’s Whip on that latest take is really good, but I’m afraid the tune itself doesn’t do anything for me - not one I envisage bothering to learn - just personal taste, no criticism implied.
Sorry Jem, I don’t know any of those tunes I listed. I was just searching the web for tunes with that pedal point passage and came up with that list. I googled “cE dEcE + abc.” Sorry you don’t like the tune, but glad you liked my playing. I usually play it at a quicker tempo.
