Did you ever wonder how many hit songs have mentioned "April"? Well, that's the kind of thing that will wander into my mind, and I just have to deal with it. So:
Hits with April in their title (since 1960):
Pieces Of April - Three Dog Night. Reached #19 in 1972.
The April Fools - Dionne Warwick. Reached #37 in 1969.
And that's it. Kind of surprised me.
Now pre 1960? Between 1940 and 1959 there were 11, including 3x top-10s. But you can look 'em up yourself!
