Something missing here? For the first time since the NCAA basketball tournament began in 1939, there are zero No. 1 seeds remaining in the Final Four.

In fact, none of the projected top guns made it as far as the Elite Eight.

Here’s how the leading lights went dark on the bracket sheet.

• Alabama was rolled by San Diego.

• Houston’s last rodeo was a loss to Miami.

• Kansas got oinked by Arkansas Razorbacks.

• Purdue speared by Fairleigh-Dickinson’s hyphen.

Furthermore, none of last year’s Final Foursome (blue- bloods Kansas, North Carolina, Duke, Villanova) are back for an encore.

Meanwhile, the guitarists, organists and drummers continue to make music as the Big Dance shifts stages to Houston.

Here’s a look at the last four kicking up their heels in the annual 68-team single elimination hoops gig.

Palm trees: It is fitting that Palm Sunday this year falls on April 2. Three of the four finalists (Miami, Florida Atlantic, San Diego) hail from palm tree locations.
