Amy Winehouse has displeased thousands of her fans after she let them wait for almost an hour at her first live concert.

Speaking to the Lisbon crowd, the "Rehab" singer said, "Hey Lisbon, I'm sorry I'm late."

She claimed she was suffering from flu-like symptoms and she struggled through her performance while eating lonzenges.

The 24-year-old Grammy-winner told her fans, "My voice is not singing right and I can't even hold the microphone. But I wanted to be here so much."

According to reports, her voice repeatedly cracked and she often dropped her microphone and talked with her band members.
