Michelle Obama joined Bruce Springsteen on stage in Barcelona, Spain, last Friday night as he and the E Street Band performed their 1985 hit, "Glory Days." However, the former first lady appeared to be familiar with only a few of the song's lyrics, including its title.

Dressed in loose purple cargo pants and a dark blazer, the 59-year-old enthusiastically played a tambourine while attempting to follow the band's choreography. At various moments during the performance, Springsteen's wife Patti Scialfa, a regular backing vocalist, guided Obama to the microphone.

Kate Capshaw, the wife of director Steven Spielberg and an actress herself, also shared the mic during the concert at Lluis Companys Olympic Stadium.

Michelle and her husband, former President Barack Obama, are vacationing with the Spielbergs in Spain, according to reports.

In March, photographers captured her frowning as her husband, 61, engaged with an enthusiastic crowd during a speaking tour in Sydney, Australia. The event marked the couple's first joint public appearance in five months.
