The band went through various different line-ups and toured extensively for the next two years. They had one commercial success, a cover version of "Woodstock" by Joni Mitchell which was a number one hit single in the UK Singles Chart in October 1970. It received heavy airplay in Canada, reaching No. 5, as well as peaking at No. 23 on the Billboard singles charts in the United States in 1971. Afterwards, Matthews left Southern Comfort, who went on to release three albums of their own on Harvest Records.
