I'm caught between the extant reviews. The key is to be old enough to have heard these songs, even if it's years since the experience. What great fun to find out what he really said in pieces like "Step Right Up" and "Pasties and a G String".
Those of us who've crossed the bar of a half-century will take "Martha" so much more to heart, now that our own Martha's are gone. We know the 'Heart of Saturday Night' - Saturday night back then - is still the best that could ever be. Pity the youngsters who never had the brilliance of a slow dance, who never had three or four too many but made it to work the next day and kept going because your 'baby' was waitin up for you. Get it, recall it, make up your own melodies when the memory's going fuzzy - it's all to the good.
