Many of his artists over the next thirty years was diverse but all were hugely successful. Kenny Young, a client from his early April Music days, sold millions of albums on both sides of the Atlantic with songs such as "Under the Board Walk" and "Captain of Your Ship." Additionally, there was Ron Grainer responsible for the themes to "Dr Who", "To Sir with Love", "Tales of the Unexpected" and the music for "Robert and Elizabeth". With clients Ned Sherrin and Caryl Brahms, the Arlons entered the arena of theatre production. Their first venture together was the acclaimed musical "Nickleby and Me", followed by "I Gotta Shoe", "Only in America", "Okay", "The Mitford Girls", and "Side By Side By Sondheim". It was Sherrin's performance in the hit Broadway version of the latter that led to his own television series "We Interrupt this week". Devised by Sherrin and produced by him and Arlon this ran for 26 weeks on WNET, America. Back in Britain, the success of "Side by Side" spawned a long running TV series "Song by Song by…" again produced by the Arlons.
