Wikipedia (click) says that Joseph Grimaldi (1778-1837) was an English actor, comedian and dancer, who became the most popular English entertainer of the Regency era.

YouTube has an album by Daniel and Laura Curtis titled The Pantomime Life of Joseph Grimaldi (click)

The two songs requested are "Iron Legs" and "Hot Codlins." Can anyone help with either? And do Iron Legs and Hot Codlins have any connection to Joseph Grimaldi the 19th-century English clown>

Here's a recording of "Hot Codlins" by the Grimaldi Band:

And here's a live performance of "Hot Codlins" by a clown, so it DOES appear to be connected to Grimaldi the clown:

Wikipedia says:

At Easter 1819, in The Talking Bird, or, Perizade Columbine, he introduced perhaps his best known song "Hot Codlins", an audience participation song about a seller of roasted apples who gets drunk on gin while working the streets of London. Songs about trades were popular on the stage in the 1800s. Grimaldi sought inspiration for the character of the apple seller by walking around the streets of London and observing real-life tradespeople.

And here's a "Hot Codlins" cartoon:

So, what about "Iron Legs"?
