Slidell lawyer Alan Black is trying to grab higher ground in his bid for 22nd Judicial District Attorney with an endorsement from superstar Stevie Wonder.

The musician’s pitch can be heard on Black’s Facebook page, in which he says, “I’m here to encourage you to vote for my friend, Alan Black, for district attorney of the Northshore; not just because he’s my friend, but because he’s honest and he’s fair.”

The Wonder imprimatur follows another celebrity nod from television heartthrob Ian Somerhalder, who touted Black’s candidacy on Instagram.

Black is in a hotly contested four-way race to succeed Walter Reed, running against Roy Burns, Warren Montgomery and Brian Trainor. It’s not clear what impact, if any, the high-profile backing will have on the race.

But Wonder’s endorsement, on election eve, is a reminder of Black’s Washington Parish ties. He met the singer when he was a 14-year-old working at Studio in the Country in Bogalusa, where the singer was recording the 1979 album “Stevie Wonder’s Journey Through ‘The Secret Life of Plants.’”

Former co-producer Gary Adante said it was Black’s job to make Wonder, his band and staff comfortable for almost a year of work.

“Stevie Wonder has been my friend for the past 40 years, and I am honored that he has endorsed my candidacy for district attorney,” Black said.

Apparently, he just called to say “I endorse you.”
