However old you are, consider that in 1968, when he was only 23 years old, Van Morrison released “Astral Weeks.” He followed that up at 25 with “Moondance,” and then “His Band and the Street Choir,” and then at 26, “Tupelo Honey.”

What had you done by the age of 26? Me, not much. Then again, by the time he was 30, Van Morrison had creatively burned out. If you ask me — though I’ll conced that 1979’s “Into the Music,” and the glorious 1988 collaboration with the Chieftains are two arguments against that position.
