Peter has written lyrics and songs for various events: congresses, company outings, anniversaries etc. He wrote and directed a musical for Kia Netherlands and was asked to write or perform songs several times on company events of the Dutch travel agency VrijUit. A touch of irony is always part of the deal, of course.

Some examples of songs Peter was commissioned to write: 'RSI' was written for an Education Conference on the use of technology in education. 'Fotowinkel' dealt with the opening of a new photo shop. 'Time to go' was witten for the farewell dinner of Lord De Ramsey, when he left the House of Lords. It was performed by Peter in London. The music of both 'RSI' and 'Time to go' was composed by Bram Stellingwerf.
