John Mellencamp explained why he “hated” one of his biggest hits on a new episode of Real Time With Bill Maher and revealed how the “stupid and silly” song ended up on his album anyway.

The song in question? “R.O.C.K. in the U.S.A. (A Salute To 60’s Rock),” the closing track on Mellencamp’s multi-platinum 1985 album Scarecrow. The song peaked at No. 2 on the Billboard 200, tying with “Hurts So Good” as his second-biggest hit behind the chart-topping “Jack & Diane.”

Despite its success, Mellencamp was staunchly against including “R.O.C.K. in the U.S.A.” on his album — but a bad bet forced his hand.

Why Did John Mellencamp Put ‘R.O.C.K. in the U.S.A.’ on His Album?

Mellencamp told Maher the circumstances that led to him begrudgingly tacking “R.O.C.K. in the U.S.A.” onto the end of Scarecrow.

“I had a song called ‘R.O.C.K. in the U.S.A.’ And I hated it,” the singer said. “I just thought, this is f—ing stupid and silly.”

Mellencamp’s record label begged to differ.

“I didn’t want to put it on the record, but I made the mistake — I never let the record companies hear my records until I present them,” he explained, “because they have A&R people that want to come in and say, ‘You need to do this, you need to do that.’ And I always say, ‘No, no, no, no.’ They’re not even gonna ask me anymore.”

He continued: “So anyway, I made the mistake of letting somebody hear ‘R.O.C.K.’ and they just went nuts. They said, ‘That’s a number one record.’ Well, it’s not gonna be on the album because it didn’t fit on the album. Back when albums had a theme. So I arm wrestled the guy, and we tied. Well, I had to put it on the record.”
