I what watching Glee and heared his name and it happens to be my hubby last name.
The song "Make 'Em Laugh" was performed on Glee. It was written by Arthur Freed & Nacio Herb Brown and performed by Donald O'Connor in the musical film "Singing In The Rain".
"Make 'Em Laugh" has lyrics that include:
"And in the words of that immortal buddy
Samuel J. Snodgrass, as he was about to be lead
To the guillotine"
Unfortunately, I cannot find any information on this line.
My source on different known Snodgrasses does not help either.
