I take a deep breath as I stand on the stage of New York's iconic Town Hall, as the audience looks on in anticipation. This is the legendary Hall for All, where the phrase "not a bad seat in the house" was born. A theatre steeped in history, renowned for championing the suffragette movement, breaking down racial barriers and giving a platform to those whom society had too often marginalised.

Eighteen months ago, I launched a GoFundMe campaign with an ambitious goal: to raise £150,000 to take musicians with learning disabilities to Broadway in honour of my friend, the late Sir David Amess.
