20 million TV viewers watched Barack Obama’s second inauguration as US president.
No surprise that it was sharply down on four years ago, when 38 million tuned in.
Beyonce lip-synched the national anthem at President Obama's inauguration to a pre-recorded backing track, The Times (£) reported.
A spokeswoman for the Marine Corps Band, who accompanied Beyonce, reportedly said the singer decided to rely on the studio version shortly before she was due to perform.
She said: “We did pre-record it and it was Beyonce’s decision at the last minute to go with the pre-recorded version. We pre-recorded all music as a matter of course and have done since time immemorial."
Video prankster Cassetteboy has turned his attention to President Obama's Inauguration.
The YouTube star uses creative editing techniques to twist the words of celebrities and politicians.
"My fellow Americans, I have sworn before you today to stand here in four years, and 40 years, and 400 years hence as King for all time," Obama appears to say.
And with questionable diplomacy, the President is seen to declare:
"Now, more than ever, we must resolve our differences with other nations with muskets and militias."
