London: Former Beatles star Paul McCartney has released a video message to assure fans that he feels "great".
A recent viral infection left the 72-year-old singer hospitalised last month and caused him to postpone a number of dates on his `Out There` tour, reported Digital Spy.
The singer insisted that he is now "feeling great, rocking and rolling" in the video.
Concerts in Lubbock, Dallas, New Orleans, Atlanta, Jacksonville, Nashville and Louisville have been pushed back until October.
McCartney was touring to promote his 2013 album New.
