“This Happy Madness” (aka “Estrada Branca”, Portuguese for “white road”) is a bossa nova song composed in 1958 by Antônio Carlos Jobim with lyrics by Vinícius de Moraes. English-language lyrics were added later by Gene Lees.-Wikipedia

What should I call this happy madness
That I feel inside of me
Some kind of wild October gladness
That I never thought I’d see
…

What happened to the frown
And is that self contented clown
Standing grinning in the mirror really me
I’d like to run through Central Park
Carve your initials in the bark
Of every tree I pass for every one to see
