I have always loved the guitar playing of Hank Marvin (The Shadows), not just because if the nostalgia it brings me, but because it’s absolutely brilliant in its precision and clarity. I forget who said it (Clapton or Jimmy Page, maybe?), but the advice given to any would-be guitar god was always: “Unless you can play Hank Marvin’s lead guitar from the 1950s and 60s perfectly, note-for-note, you haven’t really done anything yet.” It was, and remains to this day, the best foundation for any young lead guitarist.
Of course, the Shadows fell out of favor towards the end of the 1960s, as did all the old guitar instrumental bands, so Hank and rhythm guitarist Bruce Welch took a hiatus from the Shadows and formed a group called Marvin, Welch & Farrar with Australian songster John Farrar, and they made some wonderful music — this time as a vocal group — which featured close-knit harmonies which are, in my opinion, the equal of more well-known vocal groups like the Hollies or even (gasp) Crosby, Stills and Nash.
Listen to their eponymous album, especially Silvery Rain (track #5).
Time, well-spent.
