Four days later in London, McCartney began cutting the soundtrack for a projected film about the beloved Daily Express children’s character Rupert Bear, to which he owned the rights. Among the tunes recorded were ‘Rupert Song (Parts 1 and 2)’, ‘Tippi Tippi Toes’ and ‘The Castle Of The King Of The Birds’. A thirty-eight-piece orchestra and a boys’ choir joined Paul to lay down both vocal and humming versions of the rousing ‘We All Stand Together’, which would be a British hit some four years later.
McCartney was sipping a Scotch and Coke when the young choristers filed out, in a reflective mood; the song had moved him. Around midnight, a Cinderella moment in the empty studio when the gear was being stowed, he turned to Linda and one or two friends and told them that it reminded him of the famously trippy session for ‘All You Need Is Love. ‘It was that same vibe. I just looked around, and there were all these flowers and happy faces smiling up at me.’ Another sip or two, and he began murmuring huskily, ‘John… John…’ And Paul bent over chuckling, as though it had been yesterday rather than thirteen years before.
