They appeared on the ITV talent programme Opportunity Knocks with host Hughie Green and won for seven consecutive weeks, which was a record. This then led to them rush releasing their biggest hit called "Welcome Home". This was originally a French song, and was translated into English by Bryan Blackburn, and it even appeared in the Billboard charts too. It was the only UK number one. The song is part of 70s music culture, and was used to remind people of the 70s music era in a successful crisp advert in the 1990s.
The team were on TV all the time, mainly singing the same song over and over, but they did release "By Your Side" which was a minor hit in 1973. It was not until April 1974, when "Don't Stay Away Too Long" flew up the charts to No.3 in the UK.
The group were on a roll now as the next hit "Rainbow" in August got to No.17.
Then it all stopped, they released around 12 singles, but all failed to chart. Everybody just wanted to hear ""Welcome Home" again and again. Lennie Peters uncle was Charlie Watts, and in 1992 Charlie attended the funeral of Lennie who died of bone cancer.
