it was a chastened bonzo dog band who returned to the uk, and with spear rejoining them they regrouped to complete work on their fourth album "keynsham". the titular keynsham is a small town near bristol in south-west england. according to neil innes', the name of the album derived from an oft-repeated advertisement played on radio luxembourg in the 1950s and early 1960s, which promoted a method of forecasting results for football matches (and using these results in football pools). in the advertisement, which was of great length, horace batchelor, inventor of 'the amazing infra draw method', would spell his postal address of k-e-y-n-s-h-a-m for those listeners who wished to purchase his secret. batchelor had earlier been name-checked (alongside "zebra kid") performing on percussion in "the intro and the outro".
