"Prove It" is the second single from American rock band Television's debut album, Marquee Moon, released in 1977. It was released as a single with "Venus" on the B-side and became the most successful of their three hit singles in the UK. Despite entering at a (then) relatively high position of number 28, it only got up to number 25 and dropped out of the Top 40 after another week at number 29.
Like its preceding single, "Prove It" was a staple of Television's early live shows, often as a set closer. The lyrics, reflecting upon a detective story, echo the movie The Long Goodbye which came out a few years before Marquee Moon.
