[16] En 2009 Danny Hagan renunció como director, conservando sus acciones, y Ken Lower vendió las suyas.
[13] En 2018, tuvo 25000 visitantes, con cabezas de cartel como Fleet Foxes, The War on Drugs y Public Service Broadcasting.
[22] El Festival Green Man rechaza el patrocinio comercial y, por lo tanto, puede centrarse en proveedores locales de alimentos y bebidas galeses, en lugar de estar atados a acuerdos corporativos.
[23] El festival es un socio benéfico de The Bevan Foundation y Oxfam Cymru, Cymdeithas yr laith Gymraeg, RSPB Cymru y Brecon Beacons National Park Authority, todos ellos con puestos propios en el festival.
