Lieutenant Pigeon’s “Mouldy Old Dough” became one of the 1970s’ strangest chart-toppers, reaching number one in the UK for a month in late 1972. Its success was notable because the group featured pianist Hilda Woodward and her son Rob, making them the first mother-and-son act to top the UK singles chart.

The song combined boogie-woogie, honky-tonk and ragtime piano with an abrasive penny whistle and guttural repetitions of its title. Originally written for the more serious band Stavely Makepeace and recorded in the Woodward family home in Coventry, it also topped the charts in New Zealand, Belgium and Ireland, while reaching the top ten in several other countries.
