"This Can't Be Love" is a show tune and a popular song from the 1938 Rodgers and Hart musical The Boys from Syracuse. It was also included in the 1962 musical film, Billy Rose's Jumbo, though most of the songs in that film came from the 1935 Rodgers & Hart musical Jumbo. Richard Rodgers' lyrics poke fun of the common depiction of love in popular songs as a host of malignant symptoms, saying, "This can't be love because I feel too well."

The song was a hit for the orchestras of Eddy Duchin and Benny Goodman in late 1938/early 1939.

Nat "King" Cole released a version in 1954. In 1956, it was recorded by Ella Fitzgerald on her two-record Verve release Ella Fitzgerald Sings the Rodgers and Hart Songbook. In 1961, Judy Garland performed the song as a medley with "Almost Like Being in Love" in the Judy at Carnegie Hall concert. It was also recorded by Dinah Washington, Frank Sinatra, George Shearing, Tony Bennett, Johnny Mathis, Natalie Cole, Rufus Wainwright, Michel Legrand, and Diana Krall, among others.To this day the song is played by many BIG Bands.

======================
In Verona my late cousin Romeo
Was three time as stupid as my Dronio
for he fell in love
and then he died of it
poor half-wit!

This can't be love because I feel so well
no sob. No sorrow ,no sight
This can't be love I get no dizzy spells
My head is not in the skies
My heart does not stand still
just here It beats
this is too sweet to be love
This can't be love because I fell so well
but still I love to look in your eyes

Though your cousin love my cousin Juliet
loved her with a passion much more truly yet
some poor playwright
wrote their drama just for fun,
It won't run!

This can't be love because I feel so well
no sob. No sorrow ,no sight
This can't be love I get no dizzy spells
My head is not in the skies
My heart does not stand still
just here It beats
this is too sweet to be love
This can't be love because I fell so well
but still I love to lo
