Stormy weather forced Barbra Streisand to postpone her date in Austria on Thursday night (21Jun07).
Promoters for the outdoor show at Schloss Schoonbrunn in Vienna decided the elements were too hazardous and cancelled the show.
That concert will now take place on Friday (22Jun07).
Meanwhile, Streisand has been breaking records on her European tour - she recently shattered the concert house record at Zurich's Hallenstadion, where she kicked off her first ever dates on the continent.
The tour wraps up next month (Jul07) with three dates at London's 02 Arena.
