John Mayall/Al Kooper Live in Albany, N.Y.
It was almost begrudgingly that Kooper introduced a song he said they had to do "whether they wanted to or not, which turned out to be "I Love You More Than You'll ever Know, the hit he wrote for BS&T on Child Is Father to the Man featuring Randy Brecker among the horn section (prior to David Clayton Thomas days). If it truly is a song he'd rather not do (and those comments could have been sarcasm, as confirmed by the droll humor of other banter between songs), the performance wasn't perfunctory. It kicked, carrying all of the pathos and even cool that one would expect.
Kooper, 63, joked that it was nice to finally be on a bill with someone older than himself, namely Mayall. Age notwithstanding, these are two gentlemen who are still very worthy not merely of respect but our attention.
