How did Wings (band) get their name?

The band name is said to have come to McCartney as he was praying in the hospital while Linda was giving birth to their second child together, Stella, on 13 September 1971. Paul McCartney recalled in the film Wingspan that the birth of Stella was "a bit of a drama"; there were complications at the birth and that both Linda and the baby almost died. He was praying fervently and the image of wings came to his mind. He decided to name his new band "Wings".
