The song became a garage rock staple and a part of many rock bands' repertoires. It is particularly memorable for its "G–L–O–R–I–A" chorus.

 He started to perform it at the Maritime Hotel when he returned to Belfast and joined up with the Gamblers to form the band Them. He would ad-lib lyrics as he performed, sometimes stretching the song to fifteen or twenty minutes. After signing a contract with Dick Rowe and Decca, Them went to London for a recording session at Decca Three Studios in West Hampstead on 5 July 1964; "Gloria" was one of the seven songs recorded that day. Besides Morrison, present were Billy Harrison on guitar, Alan Henderson on bass, Ronnie Millings on drums and Patrick John McCauley on keyboards. Rowe brought in session musicians Arthur Greenslade on organ and Bobby Graham on drums, since he considered the Them members too inexperienced. There remains some dispute about whether Millings and McCauley were miked up, but Alan Henderson contends that Them constituted the first rock group to use two drummers on a recording. Although some sources claim that Jimmy Page played second guitar, other sources deny this. Wikipedia

Belfast reporter how the song had just happened during the first recording session for the album and the band was just "busking" around. "Someone started playing a fast riff and we all just joined in. The lyrics I sing at the end were just words from a song I had been writing at the time." Later in 1966 he told an American reporter how it was inspired by an occasion in Nottingham Park as he walked by a graveyard wall where some children played next to it. "You know, man, there was life and death beside one another so close...yet so different...And then I thought of the bright lights in the children's eyes...and the cloudy lights in the eyes of the dead."Wikipedia
