Sixes attracted enthusiasts and celebrities. Knute Rockne, George Raft, Barbara Stanwyck, and Otto Kruger were fans. Kruger used to invite riders home. Bing Crosby – whose presence at a track guaranteed he would be met by song-publishers' touts offering him music – was said to pay the hospital bills of riders who fell. The actress Peggy Joyce – her wealth was such that Cole Porter wrote a lyric that said "My string of Rolls-Royces, is longer than Peggy Joyce's" – gave regular $200 bonus prizes, or primes. She was so delighted when a band in the track centre played "Pretty Peggy with eyes of Blue" that she put up $1,000.
