The 71-year-old Grammy-winning singer, who is performing at the Nassau Coliseum in Uniondale, will give away two concert tickets to anyone who makes a donation of a new or gently used instrument, reported Ace Showbiz.
Manilow said music is "a vital part of a child's education."
The donation is part of Manilow Music Project to benefit music programs in public schools.
Uniondale Superintendent William Lloyd appreciates what the singer did and hopes it will encourage more people to help schoolchildren "build character to achieve success.
