Leonard Cohen’s latest album may have been slyly called Old Ideas, but rest assured, the great singer-songwriter-poet is still full of new ones. “I’d like to hold you baby, but my arms are old and weak,” he sings on “I’ve Got A Little Secret,” debuted in current form last week onstage in Ireland. “I was listening to your story, but I guess I fell asleep.” The wit of many songs past and his earliest work in verse remains, as Cohen has given 2011’s “Feels So Good” — a tune we shared in that first incarnation — a full revision. Watch him perform the inspired new take above.
