SYDNEY, N.S. -- Country music star Alan Jackson is postponing a show in Nova Scotia to attend the funeral of country music legend George Jones.

Jackson was originally scheduled to perform to a sold-out crowd Thursday night at Centre 200 in Sydney.

He has postponed his appearance until May 7.

Memorial and funeral services for Jones, who died April 26, are set to take place Wednesday and Thursday in Nashville.

Jackson and Jones' friendship spanned over 25 years.

In 1992, Jackson recorded "I Don't Need Your Rockin' Chair" along with Jones and several other artists, and the two also recorded a duet of "A Good Day for the Roses" for a Jones album in the early 1990s.
