天使のたまご
In January 1973, Moerlen joined Daevid Allen's Gong, debuting on the "Angel's Egg" (1973) album. In June 1973 he was asked by Virgin Records's boss Richard Branson to play percussion with Mike Oldfield for the premiere of "Tubular Bells" (1973), to replace the incapacitated Robert Wyatt. Steve Hillage, guitar player of Gong, also took part. Between 1975-87, beginning with "Ommadawn" (1975), Moerlen would be Oldfield's percussionist of choice for his albums and his tours.
