[5] He opened 18 concerts for the Beatles across the US and Canada in 1964, but his main source of income came from New Orleans's Bourbon Street strip, where he played for 19 years.

[6] Henry continued to perform into his last years and had been scheduled to appear at the 2024 New Orleans Jazz & Heritage Festival later that month.

The Band recorded a version of Henry's 1956 song "Ain't Got No Home" for their 1973 album Moondog Matinee.

On his 1981 Live/Indian Summer album, Al Stewart introduced his song "Year of the Cat" with an odd anecdote about a mistaken-identity encounter involving Henry, Audrey Hepburn, and G. Gordon Liddy wearing an Elvis Presley mask.

"Ain't Got No Home" achieved fresh notoriety in the 1990s through its use as the "Homeless Update" theme music on The Rush Limbaugh Show, and was used as recently as December 7, 2017.

[10] The song also appears in the 1995 movie Casino, playing in the background as Joe Pesci asks Robert De Niro for a 50K chip marker.
