The obituaries for rock star David Bowie waxed eloquent over his ability to change, evolve, reinvent and metamorphosize.Sadly, the SONGS of our youth don’t change as we progress through life; they possess a certain nostalgic charm, but they fail to remain relevant.True, someone will occasionally record a cover version with a different tempo, but the lyrics remain preserved in amber, no matter how much sadder but wiser we become. (As The Four Tops might declare, “It’s The Same Old Song.”)Is anyone up to the task of updating our rich musical heritage to reflect the aging process and harsh realities of life?(Granted, some songs don’t even need the title tweaked. For instance, that paean to senior moments, “I Still Haven’t Found What I’m Looking For.”)Yeah, songs about broken hearts always sell, but can’t we have some songs bold enough to deal with other health issues? You know, like “Mama’s Got A Pillbox” (with apologies to The Who) - or a reworking of songs by The Animals, especially “Please Don’t Let Me Be Misunderstood - Help Me Put My Dentures Back In.”
