Gloria - the original

In 1964 and 1965 an Irish band named THEM had three or four singles in the USA before their leader, Van Morrison, left the band for a solo career.  The song "Gloria" is arguably Them's most famous hit, even though a cover by the Shadows of Night in 1965 charted much higher.  Morrison wrote the song and it's been covered by literally hundred's of bands and artists and is a legitimate rock classic, as well as today's forgotten oldie.
