A weekly folk music show, hosted by singer Rory McEwen with help from the cream of British folk at the time. Martin Carthy, Iain Campbell, Cyril Tawney, Davey Graham, and Alex McEwan (brother of Rory), plus a side helping of British rhythm and blues provided by The Cyril Davies' All Stars with guests Long John Baldry and The Velvettes. The series was recorded at ABC's Teddington Lock studios.
To help promote the forthcoming series a version of the show was taken to the Edinburgh Festival, under the tile Straight From The Wood. "All the stars appearing in this short Edinburgh Festival season will be appearing in Hullabaloo".
Due to the occasional inclusion of visiting American acts like Ramblin' Jack Elliott, Carolyn Hester, Peter, Paul & Mary, Sonny Boy Williams ABC managed to sell the show to Australia and America, which probably accounts for so many extant editions in the vault. It began a run on Australian TV in January 1964.
In May 1964 the show was brought to the Royal Festival Hall for a live presentation featuring Rory McEwen, Isla Cameron, The Ian Campbell Folk Group, Bob Davenport, Martin Carthy, Lisa Turner and The Malcolm Price Trio.
