A 1969 favorite, "Chicago Cubs Song (Hey, Hey! Holy Mackerel!)" was written by Chicago musician Johnny Frigo, a jazz player and producer who was heard on Chicago radio for 23 years leading a band called the Sage Riders.

The lyrics were written by I. C. Hoag, who remains obscure. Credited to the Len Dresslar Singers, “Hey, Hey! Holy Mackerel!” gets its title from the home run calls of Cubs broadcasters Jack Brickhouse and Vince Lloyd.
