The Zombies had one of the British Invasion's weirdest career progressions. They formed in 1961, when singer Colin Blunstone met guitarist and songwriter Rod Argent at school in St. Albans, a London suburb, then spewed out perfect pop singles such as "She's Not There" and "Tell Her No" before peaking with a sprawling masterpiece of an album called "Odessey and Oracle." But, bereft of consistent hits, they broke up in 1967, prompting Blunstone to take a job at an insurance agency. But "Time of the Season" took off unexpectedly in the United States, and Blunstone, 68, has maintained a solo career ever since. By phone from a New York hotel, Blunstone -- who performs Wednesday at the YMCA Boulton Center in Bay Shore -- talks about this year's "On the Air Tonight," full of dreamy ballads delivered in a high, clear voice that hasn't changed since the Zombies.
