The singer moves seamlessly into his next number, Can’t Help Falling in Love. If Robbie feels me stiffen in his arms, he doesn’t show any sign of it. “Did you…” I lick at my dry lips, trying again. “Did you ask him to play this?” “No,” he says quietly in my ear. But I don’t believe him. There’s something in his voice…it’s different, not as sure and sturdy as it usually is.
