Whitney Houston's comeback tour isn't the smashing success that Clive Davis hoped for!

Last night at her Brisbane concert, fans stormed out when she failed to dazzle, singing out of tune and out of breath and even walking off stage to take a "break" after only two songs, enlisting the help of her brother Gary to carry the tune.

Concert goers described her performance to the Daily Telegraph as "embarrassing", "terrible", "poor", "rambling" and "hopeless". Others said they would be demanding a refund.

The Aussies are notoriously tough critics (Britney got a similar reception) but in this case, they may be right. Check out her attempt at 'I Will Always Love You', above and tell us what YOU think!
