you ain't the only one.. for years now i have used either sleep by the dixie dregs or sometimes i feel like screaming by deep purple as a warm-up before i play. they both help loosen the fingers.
don't know if this will make you feel better or worse but this is morse with albert lee (lee is 70) doing country boy. it isn't the best either one has ever sounded but i'd still kill to be able to play like that (and i'm not a country player) https://youtu.be/p2Wv0ZyuLhc
