In the 1971 Disney musical Bedknobs and Broomsticks, the song and dance number "Portobello Road" (written by the Sherman Brothers and largely sung by David Tomlinson) includes a reference to "Shelley" (presumably Percy):
Portobello Road, Portobello Road
Street where the riches of ages are stowed
Anything and everything a chap can unload
Is sold off the barrow in Portobello road
You’ll find what you want in the Portobello road
Rare alabaster? Genuine plaster!
