SAN FRANCISCO fans turned into the FORTY-WHINERS to blast an "embarrassing" rendition of the national anthem ahead of Thursday Night Football at Seattle.

The choice of singer seemed impeccable to some - Seattle's very own Natalie Grant, a nine-time Grammy nominee.

And her performance even had a spectacular finale - as army helicopters swooped into view above Lumen Field for a fly-over.

But while Grant's efforts were rousing to some, they were raucous to others.

As the Christian gospel songstress screeched for the top at the end of her brief act, she was met with a few unsporting responses online.

"Dear God this is embarrassing," said one viewer.

Another suggested, possibly sarcastically: "Well she hit the high note… "

But other observers blamed Seattle fans for the loud but not necessarily proud effort and atmosphere as Grant sang.

One wrote: "As in recent seasons, a whole lot of Seattle season-ticket holders sold 100-level seats to San Francisco fans for this one. "

And another argued: "Selling your 49er tickets to 49er fans should revoke your season tickets."
Unfortunately for Grant's defenders, Seattle failed to restore her honor in the following absorbing clash as the 49ers won 36-24.

The visitors led 16-3 at half-time and 23-3 after their first possession of the third quarter.
Seattle revived to trail just 23-17 before the 49ers regained control.
e threw for 255 yards and three touchdowns.

The victory put the 49ers first in the NFC West with three victories and three losses.
Seattle has now lost three in a row to also leave them with a 3-3 record.
However, San Francisco leads the Seahawks thanks to a better head-to-head record.
