"You never know what people are going through," reminded P!nk. "It's not that hard to give people a smile… we're all learning that lesson together now."
P!nk and Brandi Carlile paid tribute to Sinéad O'Connor after her death by singing her hit song Nothing Compares 2 U.
P!nk took the stage during the first U.S show of her Summer Carnival tour and invited Carlile, one of her supporting acts, to the stage as they paid their respects to the Irish singer.
"When I was a little girl, my mom grew up in Atlantic City and I used to go down to the Ocean City Boardwalk with my ten dollars and I would make a demo tape," revealed P!nk, per Billboard. "I would make a little cassette tape and imagine it was my demo for the record company."
