The Man I Love - Gershwin Piano Solo

[happy notes]

Why is the piano solo "The Man I Love" different to the "Man I Love" that comes up when you search it on the internet and someone's singing to something claiming to be "The Man I Love" but different tune, etc?  I really need some help. Thanks in advance.

The themes and tune are the same. There are just different arrangements. This song has had many many different arrangements over the years.
The piano solo follows the standard musical theatre AABA form. The A being the memorable melody while B is the bridge.
Some arrangements with singers start with an interlude and additional bridge but the main recognizable tune comes in as the chorus.
