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!

A filigreed samovar owned by the czars

A pen used by Shelley? A new Boticelli?

The snipper that clipped old King Edward’s cigars?

Waterford Crystals? Napoleon’s pistols?

Society heirlooms with genuine gems

Rembrandts! El Greco’s! Toulouse-Lautrec’os!
