It is a constant trickle of irritation in my little band. Drummer and I take pains to get note/beat perfect if practicable or necessary (although not always). Guitarist (who else?) is an exceptionally capable and talented player but always tries to shoehorn in 'doing our own version' because I believe his memory is failing - he prefers to busk things. Sometimes, as a result, we end up doing some very good alternative versions but, sometimes, it all sounds much the same. One tune in particular irritates the tits off me - no idea why particularly - we do Roachford's 'Cuddly Toy'. He insists on playing over the breakdown where there should be no guitar. Kills the song stone dead by taking away the light and shade. There, unloaded that, feels much better [/rant]
