Sombr introduced him as someone he looks up to, one of his biggest influences, a great mentor and a great person. "I grew up on this guy, I think we all grew up on this guy," Sombr told the crowd. Buckingham then took the lead on the Rumours classic with Sombr and his band behind him.
Buckingham was not the only surprise guest. Earlier in the night, Jesse Rutherford of The Neighbourhood came out to perform "Sweater Weather" with Sombr. Sombr set it up by telling the crowd he was bringing out somebody very special, and that they had better bring it.
The Los Angeles show is one stop on Sombr's You Are the Reason Tour, which runs through July 2027. The North American leg ends in late November with a pair of Madison Square Garden shows. In December, Sombr guests at four Jingle Balls, then heads to Mexico and South America in January 2027. Australia and Europe come next. The trek ends, for now, July 17, 2027 at Lollapalooza Berlin.
