John Travolta and Chad Smith made guest appearances during the Foos show on Saturday in Wantagh, NY.
Travolta appeared on stage, and Grolhl busted out the grease anthem 'You're The One That I Want'. The only rendition we've actually enjoyed.
Travolta mimed along and busted out a coupler moves from the 70s classic but didn't stay long. You can see some shoddy crowd footage below.
Then soon after Red Hot Chilli Peppers drummer Chad Smith appeared on stage to help the Foos cover the Faces track 'Stay With Me,' while ol' mate Taylor Hawkins took over the lead vocals.
