Lyor Cohen and David Weinreb attend the 2015 Boys & Girls Harbor "Salute To Achievement" Benefit  at The Plaza Hotel on May 6, 2015 in New York City. 

Real estate developer David R. Weinreb got to show off more than his business sense Wednesday night during a duet with Grammy nominated singer Vanessa Williams. The Howard Hughes Corp. CEO appeared at ease as he sang jazz standard "On a Clear Day" at a party hosted in his honor by Boys & Girls Harbor in New York City, where -- who knows? -- maybe he impressed music industry veteran Lyor Cohen, who was also in attendance.

Watch the performance -- which Williams was clearly winging -- below.

On its website, Boys & Girls Harbor touts itself as a leader in "arts infused education" that provides ways to "foster social and emotional health, academic success, and college/career readiness via exposure to the performing arts." Weinreb was being honored at the organization's "2015 Salute to Achievement," which had ticket prices ranging from $1,000 to $100,000 and was held at the Plaza Hotel. The event also featured a performance by Oscar winner Jennifer Hudson and other attendees included architect Frank Gehry, Oscar winner Gwyneth Paltrow and film producer Steven Tisch.

As you can tell by his sweet vibrato, Weinreb is no novice and in 2014 he was pulled on stage by none other than Jay Z to lead a rousing version of Frank Sinatra's "New York, New York" at a Super Bowl afterparty in NYC. Watch:
