Heart (Ann and Nancy Wilson) at the Richmond Coliseum, October 1978. The last shot in this series was exposure #38 on a 36-shot roll... a photographer can't get any luckier than I did that day.
Footnote: In June 2004 that shot was used in the liner notes of Heart's reissued Bebe le Strange album, with photo credit to Robert Bibee. Oh, well.
