"I enjoy music very much," says 66-year-old Mr Wouhra. "I also play the accordion and the harmonium. And I sing a number of ragas [Indian classical compositions]."
Mr Wouhra and his four bothers moved to the UK in 1968 and in 1972, they set up East End Foods.
Back then, it was a small company that sold pulses and rice to Indians living in the UK. Now, it's one of the country's largest Asian food companies, employing about 400 people. In 2013, it had a turnover of £180m ($243m).
Throughout, Mr Wouhra kept his passion for singing alive. " I was recording on Saturdays or Sundays when I had a bit of time," he told the BBC.
"I have written dozens of songs. I have now released six albums and I am making my own singles."
Mr Wouhra said he started singing when he was a four-year-old boy in Delhi. "My mother used to sing," he recalled.
Mr Wouhra continued to visit India often. He said he started to get serious about his singing career only in 1978 after he appeared on stage with some professional musicians. When they complimented his voice, he said, he got the confidence to chase his dream.
He kept meeting musicians from India so he could train with them and hone his skills as a singer.
Now he has a team in the western Indian city of Mumbai, the nerve centre of India's film and music industry. The team is responsible for recording the music and producing his albums.
He still travels to India where he records or performs with his team as well as other Indian singers and composers.
He also records at his home in Birmingham, where he has built a studio for himself.
Mr Wouhra also uses social media platforms such as Facebook and YouTube to share his music videos.
By his estimate, the videos have been watched by more than 50, 000 people across different social platforms.
Mr Wouhra admits that he is able to pursue his dream of singing because he can afford to spend money shuttling between India and the UK to produce his own music.
