[on how he met his wife, Julie London] The way I remember meeting her was this. I was playing the "Celebrity Room" and, one night, she walked in. I was singing a song and she walked by the bandstand and I thought, "That's one of the most strikingly beautiful girls I've ever seen". Fortunately I knew Kay Saunders, the girl she was with. Kay is the wife of Herman S. Saunders. Herm's a trio leader who's working as a casting director for Julie's ex, Jack Webb, although at the time he had a trio at the Bantam Cock. Anyhow, knowing Kay, I thought, I can easily sit down at the table and get introduced. So I was. The best way to relax is not to relax. You must keep your body and mind active. This is the best way I know to stay free from hangups. Troup died of heart attack at 80, webb of the same at 68 Blame Julie!
