"I don't know if this is legal in the city limits of Seattle." And with that, Beck tears into a spirited and funky cover of Rod Stewart's 1978 hit, 'Da Ya Think I'm Sexy?' Joined on-stage by indie rock queen Jenny Lewis, the two artists traded lyrics back-and-forth throughout the song at Marymoor Park last night (Aug. 20). Watch the fan-filmed -- and fan-approved -- video above.

The cover came near the end of the night during Beck's encore, followed by the timeless track, 'Where It's At.' It wasn't the only time during the set that Beck and company dipped into someone else's catalog; as has been fairly standard throughout his current tour, during the performance of 'I Think I'm In Love,' Beck gave fans a taste of Donna Summer's 'I Feel Love.'

Beck is currently on tour in support of his latest LP, 'Morning Phase,' through Oct. 10 when he wraps things up at the Austin City Limits Music Festival. See his full schedule here.
