It’s been said that the seeds for Woodstock were planted in South Florida. And on the Fourth of July, the sowing will be remembered with the unveiling of a small memorial at Gulfstream Racetrack.

About a year before the iconic 1969 rock festival in Upstate New York, promoter Michael Lang organized a two-day festival on the grounds of the Hallandale horse track and called it Miami Pop Festival.

More than 100,000 fans came to hear guitar god Jimi Hendrix, who played twice in one day. Frank Zappa and Chuck Berry and John Lee Hooker also performed.

Lang owned a head-shop in Coconut Grove. But things went so well at the Miami festival that he soon moved to New York, and ended up co-creating Woodstock.

Lang, now 67, is scheduled to be at next week’s unveiling along with animal rights crusader Ric O’Barry, who produced the Miami festival with Lang, and Leon Hendrix, Jimi’s axe-playing little brother.

“The second day in Miami was a washout,” said rock photographer Ken Davidoff, who shot the shows. “It is believed that Jimi wrote Rainy Day, Dream Away at the Miami Pop Festival.”

Baby drama?

Orlando resident Allison Mathis, 32, cringes at the thought that anyone would believe she’s another NBA baby mama who got pregnant for child support — and she picked the league’s biggest week to make sure everybody knew.

Mathis had a daughter out-of-wedlock with Miami Heat star and new NBA champ Chris Bosh.

Their child, she said in her first interview last week, was wanted. Mathis and Bosh lived together for two years, and she says Bosh had her get fertility treatments when getting pregnant proved harder than he thought!

“Chris really wanted us to have a baby; that’s why he had me go to a fertility doctor,” Mathis said. “I followed the treatment, and we eventually became pregnant. He was very happy when Trinity was born.”

With Bosh married to another woman, Mathis now says she’s on the edge of foreclosure and public assistance after losing her job.

And the $2,600 she gets every month from Bosh for child support won’t help keep a roof over Trinity’s head, she said. So, she’s asking an Orlando judge for more.

On Wednesday, when Mathis filed her motion, she also released an intimate video of an exuberant Bosh learning about her pregnancy.

If that bothered Bosh, however, no one would know. He scored an average 14.2 points through the series.

Neither his assistant nor his two Orlando lawyers returned calls for comment.
