Another by-product of "Tiswas"s increased audience was the boost to merchandise sales: an annual book was established, and there was a tour of universities (recognising their adult and teenaged audience) by the "Tiswas" team, under the name of the Four Bucketeers, which tied in with their spin-off album on CBS Records. This was all born out of one feature of the sixth series - "The Bucket of Water Song", which was such a hit with the viewers that it evolved from an intended one-off to an almost regular part of "Tiswas".
